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 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 , 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.

Description: The shell (Fig. 1A) is conical, elongated along carinorostral axis. The orifice (Fig. 1A’) is small and not toothed. The basis is calcareous, boat shaped, with protruding bottom. The scutum (Fig. 1B) is triangular with thick growth lines. The inner surface (Fig. 1B’) is smooth; the basal margin is convex; the lateral depressor muscle pit may be slightly developed. The tergum (Fig. 1C) is concave, with thin growth lines. The spur furrow is not deep; the articular margin is concave to nearly straight; the basal margin is convex at carinal side but sloping towards spur from both sides, the articular ridge (Fig. 1C’) is prominent at upper half. The labrum (Fig. 2A) is not elevated on either side of 74 NOTES AND NEWS

The mandible (Fig. 2C) has fine teeth, the third tooth is bifid. The maxilla I (Fig. 2D) has straight frontal margin with unequal marginal and a submarginal row of equal spines. The maxill II (Fig. 2E) is bilobed. The penis (Fig. 2F) has setules and with a sharp basidorsal point.

Distribution: Indo-Pacific-The present record for the genus and species from Pakistan is the first one from the area and fills the gap in distribution; the species is found at 21-140 m depth (Rosell, 1991).

ACKNOWLADGMENTS

The author is grateful to Dr. Arnold Ross of Scripps Institution of Oceanography, California for spenting several hours comparing her drawings with related dried specimens housed in the Marine Biology Research Division of Scripps Institution and with published illustrations and descriptions. Financial aid was provided through the University faculty grant 1998-99.
