    24 Bulletin of Zoological Nomenclature 66(1) March 2009 Case 3467 ZOSIMIDAE Seifried, 2003 (Crustacea, Copepoda, Harpacticoida): proposed emendation of spelling to ZOSIMEIDAE to remove homonymy with ZOSIMINAE Alcock, 1898 (Crustacea, Decapoda, XANTHIDAE) Rony Huys and Paul F. Clark Department of Zoology, Natural History Museum, Cromwell Road, London SW7 5BD, U.K. (e-mail: [email protected] and [email protected]) Abstract. The purpose of this application, under Articles 29 and 55.3.1 of the Code, is to remove homonymy between the family-group names ZOSIMINAE Alcock, 1898 (Crustacea, Decapoda) and ZOSIMIDAE Seifried, 2003 (Crustacea, Copepoda) by changing the spelling of the junior homonym. It is proposed that the entire name Zosime Boeck, 1873 (Copepoda) be used to form ZOSIMEIDAE, leaving the stem of the senior homonym (based on the name Zosimus A.-G. Desmarest, 1823; Decapoda) unchanged. Zosimus A.-G. Desmarest, 1823 and Zosime Boeck, 1873 are respectively the type genera of ZOSIMINAE Alcock, 1898 (Decapoda) and ZOSIMIDAE Seifried, 2003 (Copepoda). Keywords.

SANKARANKUTTY Central Marine Fisheries Research Institute THE present paper is the second in the series on Decapoda Brachyura frqm the Andaman and Nicobar Islands and reports 43 species and 2 varieties belonging to 22 genera of which genus Jonesius is new to science apart from 7 new records for the region. Heller (1868) reported 12 species of xanthid crabs from Nicobars. Later Alcock (1898) recorded 85 species and 3 varieties belonging to 33 genera including 8 species already reported by Heller. Since the first male pleopod is known to distinguish the closely related species, the same is illustrated wherever male specimens were available in the collection. Description of the first male pleopod is given for those which were not earlier des­ cribed by Chopra (1935), Chopra and Das (1937), and Chhapghar (1957).

In the present study, to clarify the distribution profile of TTX and STXs in Tetraodontidae, we investigated the composition and intra-body distribution of the toxins in Canthigaster valentini. C. valentini specimens (four male and six female) were collected from Amami-Oshima Island, Kagoshima Prefecture, Japan, and the toxins were extracted from the muscle, liver, intestine, gallbladder, gonads, and skin. Analysis of the extracts for TTX by liquid chromatography tandem mass spectrometry and of STXs by high-performance liquid chromatography with post-column fluorescence derivatization revealed TTX, as well as a large amount of STXs, with neoSTX as the main component and dicarbamoylSTX and STX itself as minor components, in the skin and ovary.

Keywords: Pufferfish, Age and growth, Reproduction, Toxicity, Gulf of Suez. ABSTRACT Some biological aspects of the pufferfish Lagocephalus sceleratus were studied and correlated with the toxicity of the fish. A sample of 176 fish with total lengths ranging from 18.5 to 78.5 cm were collected from commercial catches at the Attaka fishing harbor between October 2002 and June 2003. Length weight regression parameters for males, females and all individuals were estimated. Modal progression analysis output indicates ten distinct age groups. The parameters of the von Bertalanffy's growth model were L∞ = 81.1 cm and K = 0.26 per year. The overall sex ratio of males to females was 1: 1.3. The spawning takes place during summer and the size at which 50% of fishes are mature is 42.1 cm for males and 43.3 cm for females.

They exhibit an outstanding diversity in the numbers of extant and extinct taxa at all categorical levels. Recently, especially dur- ing the past several decades, judging from the number of publications and new taxa described, the knowledge of their systematics has increased rapidly.

  • 6. Palytoxin in Two Species of Philippine Crabs
    6. PALYTOXIN IN TWO SPECIES OF PHILIPPINE CRABS Takeshi YASUMOTO and Daisuke YASUMURA Faculty of Agriculture, Tohoku University, Tsutsumi-dori, Amemiyamachi, Sendai, Miyagi 980, Japan Yasushi OHIZUMI and Masami TAKAHASHI Mitsubishi-Kasei Institute for Life Science, 11 Minamiooya, Machida-shi, Tokyo 194, Japan Angel C. ALCALA and Lawton C. ALCALA Department of Zoology, Silliman University, Dumaguete City 6501, The Philippines ABSTRACT Two species of xanthid crab Lophozozymus pictor and Demania a1ca1ai collected on southern Negros, Philippines, were found to be highly lethal by mouse assays. The toxin in both species was indistinguishable from pa1ytoxin, a highly lethal toxin of zoanthids Pa1ythoa spp., in chroma­ tographic properties, lethal potencies and in ultraviolet absorption spectra. INTRODUCTION In tropical Pacific areas widespread rumors exist regarding the occurrence of toxic crabs (KONOSU and HASHIMOTO, 1978). The species most frequently implicated in human intoxication is Zosimus aeneus in which occurrence of saxitoxin analogues (HASHIMOTO, 1979; YASUMOTO et a1., 1981; KOYAMA et a1., 1981; RAJ et a1., 1983) and, more recently, tetrodotoxin (YASUMURA et a1., in press) have been confirmed. However, toxic principles in other crabs implicated in poisoning incidences have remained unidentified. TEH and GARDINER (1974) first reported the presence of a potent toxin in Lophozo­ zymus pictor and suggested the toxin to be different from both saxitoxin and tetrodotoxin on the basis of dose-death time relation ships and gel permeation chromatographic properties. Incidence of human fatalities due to ingestion of this species was reported on Negros Island, Philippines (GONZALES and ALCALA, 1977; ALCALA, 1983). In the same area, a human fatality resulting from ingestion of another species Demania toxica also took place (ALCALA and -45- HALSTEAD, 1970) and a related species Demania a1ca1ai was shown to be highly lethal (CARUMBANA et a1., 1976).
