the ventrals. The lateral line itself is composed of about sixty scales. The dorsal furrow 
originates under the ninth spinous ray, extending as far as the middle of the length of the soft 
portion of that fin. The sheath being composed of but one row of scales. As regards the 
shape of the scales themselves, those of the lateral line are nearly as long as deep, whilst those 
on the rest of the body are much deeper than long. Their upper, posterior, and inferior 
margins are rounded, whilst the anterior margin is obtusely angular. Smaller and irregular 
scales may, as usual, be observed upon the base of the caudal. On the opercular apparatus 
and cheeks they are large also, there being three rows of them beneath the orbit. As many as 
eight scales may be counted in the supratympanic patch, the posterior being the largest. 
As to colors, an argentine tint extends over the entire body and sides of the head. The 
upper surface of the head is brownish purple, which hue may be observed, though much less 
apparent, along the dorsal region. When the specimens are taken out of the alcohol and exposed 
for some time to the light, obsolete longitudinal darkish streaks make their appearance on the 
middle of each row or series of scales. The abdomen is yellowish and the fins yellowish grey 
or olivaceous. 
Specimens about twelve inches in total length were collected at San Francisco, California, by 
Lieutenant W. P. Trowbridge, United States army. We regret that their state of preservation 
did not allow making an accurate figure of this species. 
The male and female sexes are perfectly alike in every respect, except in the structure of the 
anterior third of the anal, as alluded to in the other species. 
The ovaries of a female, which we have examined, about the size of a large quill, on being 
opened, the ovarian membranes could be seen containing within their walls an innumerable 
quantity of immature eggs, very similar to those of Ennichthys lieermanni , figured on Plate 
XXVI, fig. 9.

DAMALICHTHYS, Girard. 
Gen. Char. —Head well developed. Eyes large. Mouth of medium size ; upper jaw protruding considerably beyond the 
lower. Teeth few in number, short, and sub-conical, disposed upon one single row. Lips of moderate thickness; lower one 
firmly attached to the symphysis of the jaw. Opercular apparatus very much developed and covered with large scales. 
Anterior portion of soft dorsal very high. Peduncle of tail slender; caudal fin deeply forked. Anal elongated, its anterior 
portion the deepest. Ventrals and pectorals proportionally large.

This genus, by its natural affinities, is more closely allied to Embiotoca than to any other of 
the same family. The most striking difference will be found in a much larger head compared 
to the body. The upper jaw is likewise considerably longer. The anterior portion of the soft 
dorsal fin is considerably higher, and the peduncle of. the tail longer and slenderer. In regard 
to the scales, it will be found that their vertical diameter is considerably greater than the
