gicalJournal' which is very accurate, excepting that the longitudinal 

 lines in the engraving are rather too strongly expressed. The apex 

 of the shell under description, the only specimem I ever saw, is 

 broken, audits actual length is 2 inches and i. It will be observed 

 that the specimen is notched at the base, but I suspect that this arises 

 from accidental distortion. 



The shell is named after my friend Sir Alexander Crichton, to 

 whose liberality I am indebted for this and the following species. 



BuLiNus iNFLATus. Bul. testd fragili, subalhidd vel fiavd, fusco 

 vel castaneo maculutd, anfractu busali castaneo fasciatd, fasciis 

 numerosis : long. -rV. l<it. -^poll. 



Hab. juxta Ambo Peruviae. 



This pretty shell somewhat approaches Bul. guttatus, brought home 

 by Mr. Cuming. The species varies very much. 



BuLiNus Pusio. Bul. testd valde ventricosd, ovato-globosd, corned, 

 diaphand, longitudinaliter striatd ; labri margine albo ; timhilico 

 mediocri : long.-i'^, lat. -.'-^ poll. 

 Hab. in maris Mediterranei insulis Grsecis (Syra). 

 This species was found in the island of Syra by Lieut. Graves, 

 during his late survey in H.M.S. Mastiff. There were but two spe- 

 cimens ; in one the umbilicus is very visible : in the other it is nearly 

 closed.
