Since my first description of this species which was based 

 in 1896 on a single fragmentary specimen, I have liad opportunities 

 to examine nearly a dozen specimens of various sizes, all preserved 

 complete in the dried state. They all came from the Sagami 

 Sea, though in only two cases can the collecting ground be more 

 exactly specified ; viz., the vicinity of Okinose in one case, and 

 Maye-no-Yodomi, 572 m. (313 faths.), in the other.
