Species of Lhnopsis. 423 



Kalimnan. — Beaumaris (G.S.V.), rare; the majority of the 

 shells referred to as L. belcher i from Moorabbin ( = Beaumaris) by 

 McCoy (loc. supra cit., p. 26), are herein described as a new 

 species, L. beauinariensis ; it was formerly doubtfully identified 

 with the Japanese shell, L. forshali, Adams, to which it bears 

 some affinity. Also " Forsyth's," Grange Burn, near Hamilton, 

 and ■• McDonald's,'" Muddy Creek (F. C. coll.).

This species is allied to L. maccoyi ; but is distinguished 

 by its bifurcating riblets and the wavy, tessellated ornament. 

 It is also rounder in outline than either L. maccoyi or L. in- 

 solita.

Description. — Shell subtrigonal, never very oblique, usually 

 thick, comparatively tumid. Nearly equilateral up to the 

 neanic stage, becoming slightly oblique in the ephebic and 

 gerontic phases. Ligament pit large and triangular. Hinge-
