probably fifteen but perhaps only twelve. Color, dull purplish gray; tentacles, 
margin (at least orally) and midventral series of pedicels, deep purple. 
Caleareous particles apparently wanting ventrally but scatteringly present 
dorsally; they have the form of crosses with nearly equal, slender, thorny arms; 
each cross is about 125» across but here and there were fragments of larger 
crosses at least 250 » across. The outer layer of skin is badly rubbed off and - 
as the crosses are in this layer, it is probable the fragmentary condition of the 
larger crosses is due to rough treatment in the trawl. Perhaps the absence of 
spicules ventrally is due to the same cause.

One specimen. 
This species appears to be well characterized by the regular arrangement 
of the conspicuous dorsal papillae but the species of Benthodytes are most per- 
plexing, particularly as they usually lack spicules or possess only such as are 
not very distinctive. Specific limits within the genus, as at present drawn, 
must be considered purely tentative. 
Benthodytes sanguinolenta.

This species is a convenient catch-all for specimens which are more or less 
elongated, have no calcareous particles, and lack any other distinctive feature. 
Whether more than a single species has been, or is here, listed under the name, 
it is impossible to say, owing to the almost uniformly bad condition of the 
material. The specimens from the following stations are from 50-80 mm. 
long and hence probably young, excepting one in fairly good condition, which is 
140 mm. long by 15 mm. thick. The specimen from 4740 appears to have 
only thirteen tentacles.
