gicalJouniar 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, ia 

 broken, andits actual lengthis 2 inches and į. It 'vvill be observed 

 that the specimen is notched at the base, but I suspectthat 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, subalbidd vel fiavd, fusco

 numerosis : long. -iV. ^«^- t-VJ^o//.

This pretty shell some^vhat 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 ; umhilico 

 mediocri : long.^^—, lat. ~[\ poli. 

 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.
