3. Bolina sp. 
There are two recognized species of Lobata on the western 
coast of North America: Bolina septentrionalis Mertens, from 
Behring Str. and B. microptera A. Ag., from the Gulf of Georgia. 
Agassiz and Mayer have described another, Hucharis grandi- 
formis, from the Fiji Islands. It is probable that the very young 
Lobata which have been taken in large numbers off San Diego 
for the past two summers belong to B. microptera, which may 
ultimately prove to be identical with Mertens’ cireumboreal spe- 
cies. But the development of these immature individuals has 
not proceeded to the appearance of the auricles, and the total 
absence of mature individuals make it obviously impossible for 
the present to determine even the family of the species with 
accuracy. 
Ord. BEROIDA. 
OCtenophorae elongated, conical or ovate, compressed, with 
large mouth and oesophagus. Tentacles and tentacle canals 
wanting. Meridional canals communicate with oesophageal 
eanals at the edge of the mouth, and send out numerous branches 
which may form a peripheral network.
