Fifty-nine specimens. 



Laganum putnami.

 specimens in either of her voyages. The original specimens are hardly more 

 than bare tests and no pedicellariae were seen. 



Peronella. 



Gray, 1S55. Cat. Recent Ech.. pt. 1. p. 13.

 in which these pores are far removed from the apical Bystem, In fact Gray 

 based his subgenus Peronella on the peculiar position of the pores, although he
