The only specimen of this shell is dead and imperfect. It is, how- 
ever, slightly mottled with brown, being most probably the remains 
of an uniform colour. It is rendered very distinct from any species 
hitherto described by the manner of its keeling. A faint elevated 
line would also appear to traverse the course of the suture. 
Hab. Baclayon, island of Bokol, Philippines. Found under stones 
at low water. 
Tripnoris cotzaris. Tri. (Mastonia) testd ovatd, acuminatd ; an- 
fractibus duodecim biseriatim granulosis, serie inferiore paululim 
maximd, margaritaced, superiore pallide fusca; anfractu ultimo 
quadriseriatim subequaliter catenato. Axis 4 lin. 
Hab. Island of Corregidor, Philippine Islands. 
Found among coarse sand at a depth of six fathoms. 
Many of these small shells have received an injury which has de- 
stroyed the mouth, and the present specimen has not escaped.

Hab. Bolinao, Ins. Luzon Philippinarum. H. Cuming legit. 
I have seen only one specimen of this very distinct small shell, 
which differs from L. fragilis (Chemn. t. 68. f. 650.) in being more 
ventricose, and having the margin nearly closed all round. In the 
latter respect it resembles L. Loscombii, Leach (Bullata; Turton). 
Found in sandy mud : ten fathoms. 
Lima ancutata, Nob. Thes. Conch. pl. xxii. f. 39,40. Lim. 
testd oblique ovatd, ventricosd, radiatim striatd, utrinque paululim 
hiante, ad marginem posticum angulatd, ad marginem ventralem 
oblique rotundatd, prope umbones angustatd ; cardine brevi; au- 
riculis parvis, posticd acutd: colore albo, 
Long. 0°90; lat. 0°60; alt. 1°10. 
Hab. Panama. H. Cuming legit. 
In form resembling L. Loscombii, from which it differs in having 
an hiatus on both sides, and a rather strong angle at the base of the 
posterior lateral margin. Collected at Panama, in sandy mud, at 
twelve to twenty fathoms.
