14 NILS HJ. ODHNER, MOLLUSCA. 
20. rosacea CHEMNITZ. Some small specimens of a bright crimson colour which 
were attached on Trochus fenestratus and other shells may be referred to this species 
as their exterior characteristics agree best with RrEEvE's fig. 46 of this form. REEVE 
gives Lord Hood's Island as locality. 
FAM. ANOMIIDAE. 
Anomia sol REEvE. 45 miles W. S. W., 60 feet ("”/-), I sp., max. diam. 
(breadth) 28 mm. It differs from the figure given by REEvE (Conch. Icon. 11, 
1859, fig. 4) in its silvery hyaline colour, and from a specimen from Madagascar in 
its narrower radiating ridges. LYNGE (1909) mentions it from the Gulf of Siam and 
gives some particulars as to synonyms and distribution. HEDLEY (1899) records it 
from Funafuti. 
FAM. PECTINIDAE. 
Pecten squamatus CGMELIN. 42 miles W. S. W., 72 feet (''e), 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 S. of Timor, Japan and Tahiti. 
P. asperrimus LAMARCK. 45 miles W. S. W., 60 feet (””/s), I sp., diam. 55 mm; 
72 feet ('"/1), I sp., diam. 33 mm. 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 HUTTON (1885) this species is distributed 
on the coasts of Australia, Tasmania, and New Zealand (cf. HEDLEY 1916). 
P. australis SowErBY. 45 miles W. S. W., 60—72 feet (""/1), 3 sps, max. 1. 50 
mm; 42 miles W. S. W., 70 feet ("/s), I sp., I. 4 mm. Distribution: Swan River, 
West Australia (REEvVE 1853, Conch. Icon. 8; HEDLEY 1916). 
P. dringi RErEvE. 42 miles W. S. W., 42 feet ("/1), 1 sp., diam. 23 mm; 45 
miles W. S. W., 66 feet ('”/7), I sp., 1. 15 mm. In form and sculpture the specimens 
are like REEVE's fig. 152a (Conch. Icon. 8), but the colour is brick-red, without 
any drawings; the right (inferior) valve is paler. — LYNGE (1909) and DAUTZENBERG 
& BavaYy (1912) comprise this species in P. fulvicostatus and give its distribution 
from Red Sea to N. and E. Australia and Paumotu TIsl. 
P. fulvicostatus ApDaAms & REEVE. 45 miles W. S. W., 60 feet ("?/), 3 sps, 
max. diam. 50 mm. They correspond to RErvE's figure 152 a but are larger in 
size. According to LYNGE (1909), this form is synonymous with P. dringi (cf. above). 
1 E, A. SmitH (1885), LyncGE (1909), and DAuUTzENBERG & Bavay (1912) consider them synonymous.
