A vvhitish band may be traced at the upper part of each whorl next 

 to the suture, and another at the base of the body-vvhorl. But this 

 species varies so much in its markings, that hardly tvvo individuals 

 are alike. Some are also rather more ventricose than others. 



Found on the šame species of Aloe and in the šame places with 

 Bul. pulchellus.—W. J. B, 



BuLiNus TiGKis. Bul. testd cylindrico-fusiformi, nitidd, subglabrd, 

 fulvo-albente longitudinaliter castaneo strigatd ; anfractibus 7 

 longitudinaliter striatis ; columelld subcallosd ; umbilico tantuni 

 non obtecto : long. 14-, lat. 4^ poli. 

 Hab. in Peruvise montibus. (Truxillo.) 



This difFers from the preceding i n many points. The body-vvhorl 

 is of considerably greater length in proportion, and the aperture is 

 consequently much longer and more acute at the upper part. 

 There is somevvhat of a callosity on the columella, and the umbilicus, 

 vvhich is small, is almost hidden by the refJected inner lip. 

 Found on bushes. — W, J. B.

Obs. After a careful (examination of numerous individuals, I am 

 unable to detect any specific characlers vvhich may be safely relied 

 on to separate the f'our varieties above described. There is indeed 

 a considerable difFerence in size betvveen the first and the lašt; but 

 1 have seen many instances vvhere food and locality have had as 

 much efFect in the developmeiit of the volume of a shell, as they
