20 CTENOPHORES OF THE ATLANTIC COAST OF NORTH AMERICA 
observer of the American Lesueuria, and I am beginning to suspect that 
this so-called Lesueuria is only a Bolinopsis infundibulum with its oral 
lobes torn off and the edges healed over to produce a rounded contour, 
for I found many specimens of this ctenophore in Halifax Harbor in 
such condition after a storm in September. 
Genus BOLINOPSIS L. Agassiz. (sens. emend.) 
Bolina, preoccupied by RaFINESQUE for mollusca in 1815.

Unfortunately, the old and familiar generic name Bolina is pre- 
occupied, having been used in 1815 for mollusca by Rafinesque. Alcinoé 
of Rang, 1828, and Mnemia of Eschscholtz, 1829, apply to a ctenophore 
which is certainly not a Bolina but is closely allied to if not identical with 
Mnemiopsis. Lesson’s Anais, 1843, was preoccupied by himself in 1840 
for birds, and Hapalia of Eschscholtz, 1825, is founded upon an imper- 
fect specimen which may possibly be a Bolina, but even so the name 
Hapalia is preoccupied for Lepidoptera by Htbner in 1816. 
Bolinopsts of L. Agassiz, 1860, is the only one of these names which 
can be applied to the genus. Agassiz instituted this name to apply to 
the Bolina elegans of Mertens, 1833, and he separated it from Bolina on 
account of the numerous, small papilla which are found upon all parts 
of the outer surface of the body, except the lower parts of the oral lobes. 
We may, however, consider this to be a specific rather than a generic 
character, especially as by so doing we will not confuse this genus with 
Leucothea (Eucharis), wherein the papille are much larger and cover the 
whole of the outer parts of the oral lobes. Moreover, the lateral pits in 
the tentacular axis, so well developed in Leucothea, are not found in 
Bolinopsis. Thus by broadening the definition of Bolina we may retain 
it under the somewhat similar name Bolinopsis. I prefer to do this 
rather than to institute a new and wholly unfamiliar name. 
GENERIC CHARACTERS. 
Lobate in which the 2 oral lobes are of medium size and not provided 
with powerful muscles as in Ocyropsis. The 4 relatively short, simple 
auricles arise from the sides of the body immediately above the mouth 
and close to the sides of the oral lobes. They are not set within deep 
grooves as in Mnemiopsis. The peripheral chymiferous tubes form 
closed circuits in the oral lobes and do not end blindly as in Deiopea. 
The auricles are shorter and the oral lobes much longer than in Lesueuria. 
The combs of cilia are small and numerous. 
The type species is Bolinopsis infundibulum of the Arctic and cold 
temperate regions.
