I have already indicated that my study of the types of 
C. micans and L. Angasi, which are in the British Museum, 
leads me unhesitatingly to declare them conspecific ; though they 
have been treated as distinctive, both generically as well as 
specifically, by Tryon. Authenticated specimens of JL. speciosa, 
received from the Australian Museum, are certainly congeneric 
with C. micans, and, in my judgment, belong to the micromor- 
phic state of that species; and in slight decrescence of the 
ornament make an approach to the varietal form, which I have 
named gracilior. Tryon thought that ZL. speciosa would prove 
synonymous with LZ. Angasi (op. cit., p. 110). The operculum of 
Pseudoliotia micans is horny, pellucid, nucleus central, four- 
whorled; the outer face is concave, obliquely and distantly 
ridged. 
Distribution.—Japan (types of C. micans/ and C. pulchella) 
and Singapore; S. Queensland (Brisbane Museum !); New South 
Wales (LZ. Angasi! and type of L. speciosa / by Angas); Victoria; 
Tasmania (Z'enison- Woods); South Australia (type of L. Angasz /). 
Pseudoliotia mieans, var. Gowllandi. 
Lnotia Gowllandi, Brazier, P.Z.8., 1874, t. 83, f. 1-2; 2d., Tryon, 
Man. Conch. X., p. 110, t. 36, f. 7-8 (copied). 
According to Tryon this species appears to him “to be 
synonymous [with Z. speciosa], judging from description and 
figure.” Certainly they are not helpful to a solution of the 
validity of the species, but thanks to Mr. Hedley I have received 
four specimens of Brazier’s shell, which permit me to offer the 
following observations :—JZ. Gowllandi is a micromorph, and like 
other small states of C. micans (as var. gracilior and speciosa) has 
only two keels instead of three on the upper surface of the body- 
whorl; moreover, there is a tendency to fusion of the two 
peripheral keels and to obliteration of the basal rib, and in con- 
sequence of the latter feature the threads on the base radiate 
uninterruptedly from the periphery to the keel. The same form 
occurs at Western Port, but of the many examples of it under 
observation some show variability in this particular towards 
differentiation of the keels. 
Localities.—Percy Island, N.E. coast of Australia (Brazier’s 
type); Milne Bay, ‘New ane: (C. Hedley!); Port Western, 
Victoria (R. Tate!).
