10 RULIJA. 



T. RUGATA, Reeve. PI. 5, fig. 56. 



Wliitish or light brown. Length, I'l inches. 



Habitat unknown. 



The pertinence of this species to the genus is very doubtful. 

 I have not seen a, specimen of it. 



T. MODESTA, Powis. PL 5, fig. 57. 



Yellowish, longitudinally strigate or maculate or nearly 

 covered with chestnut-brown, with a white central band. 



Length, '8-1 inch. 



Panama. 



Quite as closely related to Knfhria as to the type of this 

 genus. 



T. SUL.CATA, Kiener. PI. 5. fig. 58. 



Yellowish white, under a rufous epidermis. Length, 15 mill. 



Habitat unknown. 

 T. EtTRYTOiDKs, Carpenter. 



White, with a revolving series of brown rnaculations on the 

 periphery ; sometimes the base is brown, or the whole surface 

 brown spotted ; with about twenty longitudinal riblets, becom- 

 ing evanescent towards the aperture ; aperture subquadrate, lip 

 scarcely thickened, striate finely within, columella abruptly 



truncate. Length, *3 inch. 



Cape St. Luca*, Lower California. 



Has not been figured hitherto, and the specimen before me 

 (an author's type) is not in good condition for illustration. 

 Vcrj- probably the species is not a Tntncarin, at all; its si/e 

 indicates close relationship with Golumbella. 



T. TRIFASCIATA, A. Ad. This name is given in the %k (Jenera of 

 Recent Mollusca," but I have not found a description of it. 



<J<mis BULLIA, (irsiy. 



Animal without eyes ; tentacles long and slender. Foot enor- 

 mously expanded, and bifid behind in the typical species. Then- 

 is no operculum. 



Iliillia (restricted sense) has a raised band of enamel round the 

 sutures of the whorls as in AnHUnria. The animal has the 

 faculty, according to M. Quoy, of absorbing, through the pores of 

 its foot, a great t|iiaiitity of water, which it ejects when disturbed.
