Type in my collection. 



A pretty little conic species, with minute spiral striation. The 

 colour pattern appears always to consist of very narrow brown spiral 

 lines on a cinereous ground. I am unacquainted with any very nearly 

 allied form, and the only other species of Helicina I have seen from the 

 Pelew Islands is that which, originally recorded as 77. Fischeriana, 

 lias been described by M. Ancey as H. rufocallosa and Mr. Pilsbry 

 as 77". Rabei. This appears to be a variable shell of tbe group of 

 77. Fischeriana and 77. suprafaseiata, and is now figured for the 

 first time (Fig. II).
