G. 9628. Several fragments of a species allied to S. cinefa, 

 Hutton ; from the " Comis-heds," Mokihinui. 



G. 9629. Broadly costate and tuberculate at the periphery of 

 the body-whorl ; from Port Hills, Nelson. 



Genus TYLOSPIRA,' nom. nov. 

 Pelicaria, auctorum. 



Spire elevated, conical, whorls partially or entirely covered by 

 a deposit of enamel, in which List-mentioned character it differs, 

 chiefly, from Struthiolaria. This enamel may be quite thin, so 

 as to form a mere film, or it may consist of thick, callous material 

 covering the whole spire, rendering the shell almost spherical. 



In reference to Pelicaria, see p. 218.

The mode of growth of the shell of this species is very 

 remarkable. Unfortunately the protoconch is not preserved in 

 any of the specimens in the Museum collection ; the whorls which 

 immediately succeed, and which, presumably, constitute the brephic 

 stage, are boldly spirally lineate, each of the small whorls having 

 from six to seven lineations ; with growth, longitudinal striations 

 make their appearance, and these eventually give rise to small 

 nodulations on crossing the spiral lines, the surface of the shell 

 at about the commencement of the neanic stage being cancellate, 

 with the exception of a broad, sloping area surrounding the suture 

 posteriorly, which continues smooth and bears three or four spiral 

 cords with smaller lineations between ; the growth of the neanic 

 stage was evidently very vigorous, longitudinal costte are developed 

 on the anterior half of the whorls, and the nodulations at the 

 periphery become fewer in number but progressively larger until
