A. Porcupine” Specimens. 
1. ATyzostoma cirriferum, F. S. Leuck. 
Seven individuals were found on two examples of Antedon 
hystrix, P. H. Carpenter, probably from the cold area. This is a 
new host, the species having been hitherto met with only on Ant, 
rosacea. It has since been found on Ant. petasus as well. 
2. Myzostoma gigas, Liitken, MS. 
Hab. Antedon eschrichti. Station 57. Lat. 60° 14' FT., long. 
6° 17' W. 632 fathoms. Temp. 30°-5 F. 
Two individuals were obtained, but in such a distorted condition 
that they cannot be accurately determined. As, however, the 
numerous Myzostoinida infesting Ant. eschrichti at the most widely 
separated localities invariably belong to this species, those obtained 
by the “ Porcupine ” are probably of the same type. It will be 
fully described in the “ Challenger ” Keport.
