We may repeat, however, what we noticed in our description of 

 H. Phillipjri in our former Paper that the teeth vary much in 

 form, size, and numbers, according to the age and size, and perhaps 

 sex of the individual. 



The spiracles are distinct, larger than in H. Phillippi, and placed 

 a little under the eye, and in a vertical line distinctly behind the 

 eye. The lateral line is straight and continuous from the supra- 

 orbital ridges. The first dorsal fin is high and falciform, the 

 height is exactly twice the length of the portion of the base 

 attached to the back, the spine is slight and acute and half the 

 length of the fin. The second dorsal is shaped like, but less in 

 height than, the first, and its base of attachment to the back is about 

 the same ; the distance between the two dorsals is equal to that 

 between the second dorsal and the commencement of the caudal 

 fin, and to that between the first dorsal and the eye. The pectorals 

 are large and triangular, and about equal in length to the caudal. 

 The ventrals are situated in a line intermediate between the two 

 dorsals, the anal commences distinctly behind the second dorsal, 

 and does not nearly reach the caudal. The lower lobe of the 

 caudal is very deeply and less than rectangularly notched. 



The coloration and markings are not by any means distinct, the 

 specimen having evidently been long in spirits, but the remains 

 of numerous dark brown bars across the back present a very 

 different style of marking from the other known species of 

 the genus. The best description of this Fish is to be found 

 in Perry's United States Exped. to Japan (Vol. 2 p. 285 PI. 

 13 fig. 2), in which Brevoort describes a young specimen of 8 

 inches in length. We quote his description, because it is probably 

 the only instance of a description taken of this species from a fresh 

 specimen. It must be noted however, that it was little more than 

 an embryo. " Its general colour is of a pale sepia-like brown, 

 darker on the back and fins, with a pinkish tinge on lower parts 

 of the body. Irregular bands and large blotches of several shades 

 of the same brown are distributed from the pectorals to the caudal, 

 grouped in five principal bands with smaller ones near the back, 

 between the first three large ones ; the first of these is just back of
