Fast-Indian and the West-Indian species, and it therefore seems advisable to retain 
the names adopted by him. The West-Indian form was identified as lineata by 
Tryon !4, who followed Mérch !° in referring to it the shell figured by Knorr [ Vergniigen 
der Augen, iii. t. 14. fig. 4 (1768)]; this latter was named Buccinum lineatum by 
Gmelin [in Linn. Syst. Nat. ed. 18, p. 3493 (1791)], but the figure quoted agrees 
better with the East-Indian ZL. scabra, the general form being more slender and the 
coloration more chequered than in L. angulifera. There is, moreover, another well- 
known species of Littorina called lineata by Lamarck, d’Orbigny, and Philippi. The 
name striata (Schumacher, 1817) would be more applicable to this species than 
angulifera, and also have priority; but I refrain from introducing it, as there is 
already a well-known L. striata, King (1831), = canuriensis, d’Orb. (1836-43), living 
on the Canary Islands, Madeira, and the Azores.

whorl, with some smaller ones between them; greyish-white, with many small dark brown or black 
streaks; columellar lip white, 
Hab. W. Costa Rica: Punta Arenas (Grsted ®, Biolley). 
S. Panama: Panama (Sowerby 177), on the trunks and branches of small trees, which 
were growing between half-tide and high-water levels (C. B. Adams‘). 
Also found in Colombia—Tumaco (Hopke, in Mus. Berol.) ; and Ecuador—Puna, 
near Guayaquil (Eydour & Souleyet ®). 
The record of its occurrence on the shores of Peru and Chile ® requires confirmation. 
Tryon® quotes also L. costulata, Souleyet, as synonym: Eydoux and Souleyet, 
however, have simply used a French term, “ L. costulée,” on the plate; in the text, 
p. 561, they use a Latin name, L. varia.
