Dr. Stimpson enumerated 52 species, but we can easily add 125 
species to his list. Among the more interesting of these are 
species of Het Ss Sagitta, Chetoderma, Thalassema (asmall

is a slight constriction, below which the basal portion bears about 31 suckers, like 
those on the other arms. The modified portion of the arm is considerably longer 
than the distance between the Riakiaiin at its base and the interbrachial web, 
and equal to one half the total length of the oa which bears suckers, The cor- 
responding arm on the left side is of the ordinary form and has about 51 suckers.

I first dredged this Troecenting species Sse on the ‘‘Mosswood” in company 
with elites Baird, in honor of whom I have named it. It was kept alive sev- 
eral days, and Mr. Emerton made some anes drawings of it while living. Iti 
somewhat related to O. Grenlandicus Dewh., but the male of the latter has the third 
right arm much longer, with the modified portion relatively very much smaller and 
quite different in form, and with more numerous folds, and the basal part bears 4 
to 43 suckers; the dhe arms also have more numerous suckers; the web is less 
extensive and the body is more elongated.
