14 NILS HJ. ODHNER, MOLLUSCA. 
20. rosacea Curmnitz. Some small specimens of a bright crimson colour which 
were attached on T'rochus fenestratus and other shells may be referred to this species 
as their exterior characteristics agree best with Rrrve’s fig. 46 of this form. Rrtve 
gives Lord Hood’s Island as locality. 
FAM. ANOMIIDAE. 
Anomia sol Reeve. 45 miles W. 8S. W., 60 feet ('%/7), 1 sp., max. diam. 
(breadth) 28 mm. It differs from the figure given by Reve (Conch. Icon. 11, 
1859, fig. 4) in its silvery hyaline colour, and from a specimen from Madagascar in 
its narrower radiating ridges. LyNGeE (1909) mentions it from the Gulf of Siam and 
gives some particulars as to synonyms and distribution. Hrptry (1899) records it 
from Funafuti. 
FAM. PECTINIDAE. 
Pecten squamatus GMELIN. 42 miles W. 8. W., 72 feet (*«), 1 sp., diam. 45 
mm. Like fig. 82 in Reeve (Conch. Icon. 1853) in colour and sculpture; the upper 
valve with 5 squamous ribs, between which run 3 minutely spinose riblets; on the 
inferior valve there is about each second riblet spinulose. The specimen differs from 
Reeve’s figure in its strikingly unequal ears, in which characteristic it resembles 
P. squamosus GMELIN; the anterior ear is much larger than the posterior one. REEVE 
(Conch. Icon. 8, 1853) gives the Philippines as the locality of this species, DauTzen- 
BERG & Bavay (1912) record it from 8. of Timor, Japan and Tahiti. 
P. asperrimus Lamarck. 45 miles W. 8. W., 60 feet (°"s), 1 sp., diam. 55 mm; 
72 feet ('°/:), | sp., diam. 33mm. The species differs from P. australis in the existence 
of many equal-sized intercostal lines between and on the sides of the ribs; in P. 
australis, which may perhaps be a variety of the present species,’ there is one narrow 
line on each side of the ribs. — According to Hurron (1885) this species is distributed 
on the coasts of Australia, Tasmania, and New Zealand (cf. Hepiey 1916). 
P. australis Sowrrsy. 45 miles W. S. W., 60—72 feet (''/7), 3 sps, max. 1]. 50 
mm; 42 miles W.S. W., 70 feet (*/s), 1 sp., 1. 4 mm. Distribution: Swan River, 
West Australia (REtvE 1853, Conch. Icon. 8; Hepiry 1916). 
P. dringi Rerve. 42 miles W. S. W., 42 feet (°/7), 1 sp., diam. 23 mm; 45 
miles W. 8S. W., 66 feet ('°/7), 1 sp., 1. 15 mm. In form and sculpture the specimens 
are like Rerve’s fig. 152a (Conch. Icon. 8), but the colour is brick-red, without 
any drawings; the right (inferior) valve is paler. — Lynce (1909) and DautTzENBERG 
& Bavay (1912) comprise this species in P. fulvicostatus and give its distribution 
from Red Sea to N. and E. Australia and Paumotu Isl. 
P. fulvicostatus Apams & Rerve. 45 miles W. S. W., 60 feet (*%/7), 3 sps, 
max. diam. 50 mm. They correspond to Rerve’s figure 152a but are larger in 
size. According to LyNGE (1909), this form is synonymous with P. dringi (cf. above). 
1. A. Sairn (1885), Lyyce (1909), and Daurzenperc & Bavay (1912) consider them synonymous.
