NOTES AND NEWS REPORT OF CONOPEA CALCEOLA (ELLIS, 1758) (CIRRIPEDIA, BALANOMORPHA, ARCHEOBALANIDAE) FROM KARACHI WATERS Quddusi B. Kazmi Marine Reference Collection and Resource Centre, University of Karachi. The cirripedes have a practical importance chiefly from the profile growth forms on all submarine objects. In some places the large forms of Balanus are eaten, the flesh resembling that of the lobster. There is a dearth of literature on the cirriped fauna of Pakistan. They are still practically unknown. However, some work has been done on cirripedes by Annandale early in 1909, then by Moazzam and Rizvi in 1978 and 1982; Ahmed et al, 1982; Mustaquim and Javed, 1993 and lately by Javed and Mustaquim in 1994. Some unofficial reports of barnacles have been published (MRC Newsletter 1995), including one unidentified (may belong to Acasta ) embedded in coenosarc of gorgonid collected as epizoic on a majid crab Camposcia retusa . The present report is another of gorgonia associated barnacle, collected from a dry piece of colony obtained from a fishing boat at Bulleji (Karachi) in 1998. The collection is housed in MRC under the catalogue No. MRC CRI 6. Systematics Genus Conopea Say, 1822 Conopea calceola (Ellis 1758) (Figs. 1-2).

  • The Cirripedia of New Caledonia
    The Cirripedia of New Caledonia Diana S. lONES Western Australian MlISeum [email protected] The Indo-Pacific deep-sea benthos was investigated by major expeditions such as those of «Challenger» (1873-1876), «Investigator» (1884-] 887), «Valdiva» (1898-] 899), «Siboga» (1899­ 1900), «Albatross» (1907-1910) and «Galathea» (1950-52). However, none of these expeditions col­ lected in the waters of New Caledonia and its surrounding areas. The cirripede fauna of the region was first documented through the brief report of Fischer (1884), who described the shallow water bar­ nacles of New Caledonia. Fischer briefly listed 15 species from specimens deposited in the Musee de Bordeaux by the missionaries Montrouzier and Lambert. From that time, there was no documenta­ tion of the fauna until the latter half of the 20th century, when a rigorous collection and taxonomic program was conducted in the region supported through IRD (ORSTOM) and the Museum national d'Histoire naturelle, Paris. Since 1978, numerous barnacle specimens have been collected in the deep waters off Vanuatu (MUSORSTOM 8 1994), New Caledonia, the Chesterfield and Loyalty Islands (BIOCAL 1985, MUSORSTOM 41985, LAGON 1985, MUSORSTOM 5 1986.CHALCAL2 1986, SMIB21986.SMIB31987.CORAIL2 1988,MUSORSTOM61989.VAUBAN 1989,ALIS 1989, SMIB61990,BERYX21992,BATHUS21993,SMIB81993,HALIPR0219(6),the Wall ace and Futuna Islands, Combe.

Examination of these collections has yielded an exceptional diversity of thoracican cirripedes. Buckeridge (1994, 1997) provided a comprehensive account of the deep-sea Verrucomorpha (Cirripedia) from collections made by several French cruises in the New Caledonian area and the Wallis and Futuna Islands.

[email protected] 1. Breve definição do grupo e principais características diagnosticantes A superordem Thoracica pertence à classe Thecostraca e à subclasse Cirripedia (cirri / cirros - apêndices torácicos modificados). Os cirrípedes (“barnacles” em inglês) são crustáceos cujos adultos são geralmente sésseis e vivem fixos a um substrato duro ou a outros organismos. O corpo dos cirrípedes é envolvido por uma carapaça (manto) que na maioria das formas segrega uma concha calcária, o que levou, no século XIX, à sua identificação incorreta como moluscos. Os cirrípedes também incluem as superordens Acrothoracica (“burrowing barnacles”, vivem em buracos de substrato calcário e têm os apêndices torácicos localizados na extremidade do tórax) e Rhizocephala (parasitas muito modificados, sem apêndices torácicos), podendo os Thoracica (apêndices torácicos presentes ao longo de um tórax bem desenvolvido) ser considerados como a superordem mais importante dos Cirripedia por serem o grupo mais diversificado, abundante e conspícuo, já tendo sido designados como os verdadeiros cirrípedes (“true barnacles”) (Newman & Abbott, 1980).

ANDERSON AND E.A. EGAN School of Biological Sciences, University of Sydney, Sydney, NSW 2006, Australia ABSTRACT. Hexaminiusfoliorum n.sp. is described and separated from H popeiana Foster on differences in adult and larval anatomy, supported by differences in cirral activity, copulatory activity and breeding. Structure, function and reproduction in Hfoliorum are more specialised than in H popeiana. The differences are related adaptively to the occupancy by H popeian.a of a variety of hard substrata, but not mangrove leaves, and the confinement of H foliorum to the ephemeral habitat of immersible mangrove leaves. Hexaminiusfoliorum may be a specialised descendant of H popeiana. ANDERSON, D.T., J.T. ANDERSON & E.A. EGAN, 1988.

SESSILE BARNACLES (CIRRIPEDIA) FROM THE PAKISTAN COAST S.H~ Niaz Rizvi and M. Moazzarn National Institute of Oceanography, Karachi, Pakistan (SHNR) and Marine Fisheries Department, Government of Pakistan, Karachi, Pakistan (MM) ABSTRACT: The taxonomy of sessile cirripeds from the Pakistan coast is described. Out of the 15 species, seven are reported for the first time from the area. Specific taxonomic characters of all the species are described and their previous records from adjacent areas are discussed. KEY WORDS: Sessile barnacles, Cirripedia, Pakistan coast. INTRODUCTION The cirriped fauna of the Pakistan coast is not well known. Annandale (1906a, 1906b, 1906c, 1910) was probably the first to have shown the presence of barnacles in his collection from Pakistan. Stubbings (1936, 1940) mentioned some barnacles in his collection from the Arabian Sea. Moazzam and Rizvi (1978, 1982) described pedunculate barnacles from Pakistan, while rhizocephalan cirripeds are described by Moazzam and Moazzam (2004). Hassan (1963) described the distribution of Balanus amphitrite amphitrite along the Pakistan coast. Javed and Mustaquim (1992) and Mustaquim and Javed (1993) reported the occurrence of Chelonibia patula and Chelonibia testidunaria and Kazmi (2001) recorded Conopea calceola from the Pakistan coast. Barnacles have also been reported in a number of papers on the ecology and distribution of marine animals; noteworthy among them are Murray (1880), Haq et al (1978), Ahmed et al (1978) and Javed and Mustaquim (1995).
