The English species, Aporrhais pes-pelicani, has the outer lip 



expanded in two pointed projections and the shell is strongly tuber- 



culated. The animal in shape is not unlike that of A. occidentalis, 



the color, however, is quite different. Forbes and Hanley, quoting 



Johnson, state that "It is of a general yellowish-white hue, the ten- 



tacula mingled yellow and scarlet; the snout and head thickly speckled 



with scarlet, markings of which color are more sparingly distributed 



on the paler body and sides of the foot; sometimes they are not present. 



We have always found it very sluggish and unwilling to display 



itself when captured." Jeffreys says "It is shy, slow and awkward 



in its movements." In these habits it is very different from the 



American species, which is extremely active, as above described. 



As no mention is made, in the English species,' of the curious appendage 



on the ventral side of the foot posteriorly, which had it occurred would 



certainly have been observed indicates that the two forms are widely 



different. 



TURBONILLA NIVEA Stimpson 

 PI. III. Fig. 19. Length 7 mm. 



The muzzle is rather long, narrow at its base and roundly bifur- 

 cated in front. The tentacles are short and round at their tips. The 

 eyes are on the inner base of the tentacles and rather close together. 



MENESTHO ALBULA MoUer

The animal is uniformly white, mottled with opaque white gran- 

 ules, the foot broad and square in front, extending some way beyond 

 the muzzle which is broad and short. Tentacles with eyes at their 

 outer bases on slight swellings. On the upper anterior surface of the 

 foot are two rounded areas of white granules closely crowded.
