366 Additional Notes on the Holconoti. 
males the sexual apertnre is at the sommit of a projecting conical 
ila. The genus E’mbiotoca as first established, does vot re- 
quire modifications ; I have only to add a new species to it, and 
to mention some features by which it differs from the following 
genera: he spinous portion of tne dorsal is uniformly low, so 
that the soft portion rises abruptly to a much greater height; the 
atterior articulated rays of the anal simple and not branching at 
their extremity. In the male the anterior articulated rays of the 
anal are swollen near their base, forming a continuons longitudi- 
nal ridge on each side of the fin. This ridge is variously modified 
in the different species. The jaws are moderately protractile; 
the lower lip is fixed by a frennm to the symphysis of the lower 
maxillaries, and not free and moveable all round the jaw. The 
young of the third new species of this genus resembles exactly 
those of the two formerly described, but differ remarkably from 
those of another species belonging to a new genus whick I shall 
mention below, thus showing that there are generic modifications 
in the growth of the young, thongh the mode of reproduction Is 
exactly the same in all. In Embiotoca proper, the yonng resem- 
ble most remarkably the mother, about the time of their escape 
from their confinement, except in color ; in addition to the pecu- 
liarities described in my former paper, I would mention a large 
black diffused spot upon the anterior part of the soft portion of 
the dorsal and of the anal, which is found in the young ol all 
three species of this genus, whilst ZB. Caryi alone shows signs 
of it when full grown. 'The male papilla is rather large. 
E'mbiotoca Caryi.—1 possess the most complete series of this 
species, for besides two pregnant females with young ready to 
escape, caught in July, I have males and females of various s1Zes 
caught in January ; at this period the marsupial sac is reduced to 
a fusiform tube, extending from the sexual aperture to the an- 
terior extremity of the air bladder, but the state of preservation 
of the intestines did not allow a minnte examination of its sine 
ture. The male, which is more elongated than the female, has 
also much brighter colors: the longitndinal and transverse bands 
of the body are more distinct, the black specks upon, the soft 
dorsal and the anal are more brilliant, and the cheeks, opercule, 
jaws and chin are adorned with bright blue blotches more OF less 
e~nfluent ; the ground color of the body seems to vary from 
olive on the back toa yellow-orange upon the sides. see 
_ Embiotoca Jacksoni—The form of the male does not differ 
quite as much from that of the female in this species, a8 1) a 
preceding, though it is also slightly narrower. ‘The color, as 
as I can jndge from alcoholic specimens, is of a deeper olive 
green, whilst the female is more yellowish. in ay

general form and appearance, but seems to bring forth its you?’
