PACIFIC SCIENCE, Vol, XXII, July 1968 
etymology: Named after my colleague Dr. 
Edward Brinton, scientist in the NAGA Ex- 
pedition. 
description: Appeared to be represented by 
only the anterior nectophores. These bells pre- 
sented two teeth in the dorsal part of the 
ostium. The teeth are long and cylindrical, like 
fingers, and are inclined toward the opening of 
the nectosac (Fig. 3). 
The mouth plates are of mitten shape. They 
lock together at the middle by the free finger 
protuberance in such a way that the left mitten 
locks with the finger to the outer part, and the 
right mitten to the inner part, that is, toward 
the opening of the nectosac. 
The somatocyst is long and thin, reaching up 
to near the midlength of the nectophore.

Fig. 3. Sulculeolaria brintoni n. sp., superior 
nectophore in various views (14 mm high). A, Left 
view; B, right view; C, dorsal view; D, ventral view. 
The commissural canals reach up to the pos- 
terior third of the length of the lateral canals. 
The ventral canal either joins the right commis- 
sural canal (Fig. 3) or goes straight to the point 
at which both commissural canals meet. 
The anterior nectophores of the seven other 
species of the genus Sulculeolaria are illustrated 
(Fig. 4) for comparison with those of S. 
brintoni n. sp. The size of the bell is variable; 
for instance, the superior nectophores of S. 
monoica ranged in length from 5 mm to 22 
mm. Therefore, again, only the specimen size 
is given in the figure legends. 
The differential morphological characteristics 
of the superior nectophores of the eight species 
of the genus Sulculeolaria are summarized in 
Table 2. 
distribution: See Table 3.
