Hab. ad Peruviani. (Payta.) 



The transverse scaly strue are so arianged as to present three 

 and sometiiiies four smaller interstitial ones bet\veen the more 

 elevated. The scales on the slrim are suberect, and very numerous 

 and rainute. The abrupt descent from the angle to the suture 

 gives the \vhorIs, more especially the lašt, a coronated appearance. 

 Found in sandy mud, at the depth of six fathoms. — W, J, B.

Genus Typhis, De Montfort. 

 De Montfort, after referring to Murex pungens,Brander, as the 

 type of this genus, adds : " La coąuille qui nous šert de type pour 

 l'ėtablissement de ce genre n'est encore bien connue qu'a l'ėtat 

 fossile ; quoique Bruguiėre dise tres-positivement que son analogue 

 marin existoit a Londres dans le cabinet du Docteur Hunter, fait 

 que malheureusement nous ne pouvons point verifier, mais que 

 cependant nous devons adopter d'apres les profondes connoissances 

 et la perspicacitė qui distinguerent si eminemment ce conchyho- 

 logue francois." In the Dictionnaire des Sciences Natiirelles the 

 statement of Bruguiėre is noticed ; but M. Blainville observes, that 

 he was not fortunate enough to find the shell.- 1 have examined the 

 Hunterian Collection in London, with the assistance of Mr. Clift 

 and Mr. Owen, with no better success. It may, perhaps, have been 

 in the cabinet of Dr. William Hunter, now at Glasgovv; but on 

 Consulting Captain Laskey's ' General Account of the Hunterian 

 Museura* there, I find no mention of the shell. Be this as it may, 

 1 am now enabled to lay before the Zoological Society five recent 

 species of Typkis ; having been led to the inquiry by finding two 

 species in Mr. Cuming's collection, and having been supphed with 

 one from this Society's Museum, and vvith tvvo bj' the liberality of 

 Mr. James Sowerby and Mr. George Sowerby.— W. J. B.
