his collections represent an intermediate form, if not this form, which 
was described by Giltay from Bermuda.

(1 ov.), 1 female. Also 1 male, station E 17, same area and date.

This minute species, which indicates, in the comparatively short 
cephalic segment, a transitional phase between Anoplodactylus and 
Halosoma, is evidently widely distributed. It may have been con- 
fused with A. petiolatus as a member of the sargassum fauna. As 
Lebour has shown, the species described by Marcus under this name 
is not the same, and for it I propose the new name Anoplodactylus 
brasiliensis. These specimens from Virginia and Texas agree, in the 
proportions of the joints of the ovigers, as well as in the presence of 
small tubercles on the lateral processes, with the European forms as 
described by Dohrn and Lebour. It is easily separable from A. 
petiolatus on the basis of the smaller size, presence of small spinose
