186 PUSIA. 



species that " the}^ are usually found associated with Engina 

 mendicaria, which they resemble so closely in shape and color as 

 to be easily mistaken for small specimens of the latter species. 

 Mr. Crosse's figure, which is slightly enlarged, very correctly 

 represents the usual form. They, however, frequently differ in 

 being more slender, and the ribs are sometimes nearly obsolete. 

 Animal black. The foot is oblong, margined with yellow, slightly 

 auriculate in front, and about three-fourths the length of the 

 shell. Siphon rather long, irrorated with white. The pale ten- 

 tacles are marked by two black zones." 



T. LOTA, Reeve. PL 54, fig. 570. 



Pale reddish orange, variegated with brown. Length, '75 inch. 



Me of Ticao ; Philippines. 



A species of no determinate character, closely allied to or 

 identical with T. microzonias, Lam. Sowerby considers it a 

 synonym of T. pisolina, Lam., a species which I believe to be 

 identical witli T. dermestina. 



T. GLANDIFORMIS, Reeve. PI. 54, fig. 571. 



White, variegated with brown. Length, -5 inch. 



Red Sea ; Indian Ocean. 



Messrs. G. and H. Nevill say that T. dsedala, radius and this 

 species are identical, running together through intermediate 

 forms ; the types are so different, however, that having no series 

 of specimens by which to verify this for myself, I prefer to keep 

 them distinct. 



T. CITHABA, Reeve. PI. 55, fig. 599. 



Light purple-brown with a narrow, pale hand. H., '75 inch. 



Hob. unknown. 



T. APPROXIMATA, Pease. 



Shell ovate, turreted ; whorls convexly angulated at the sutures, 

 longitudinally ribbed, crossed by impressed striae ; interstices 

 punctured ; aperture striated within ; columella four-plaited. 

 Color white, banded and blotched irregularly with chestnut- 

 brown. 



Sandwich Islands. 



Not figured. Not seen by either Mr. (rarrett or myself.
