REPORT ON THE SHOEE FISHES. 71 



the riglit side. All the scales on the left side strongly ctenoid ; those of the blind side 

 are nearly smooth on the anterior half of the body, and more conspicuously serrate on 

 the posterior. One nostril situated between the eyes, the other above the lip. Eyes very 

 small, the upper slightly in advance of the lower ; interorbital space equal to the width 

 of the orbit. Snout contained twice and two-thirds in the length of the head. Ansrle of 

 the mouth much nearer to the end of the snout than to the hind maro-in of the s;ili-cover 

 behind the eye. Tail not much elongate. The height of the body is two-sevenths of the 

 total length (without caudal), the length of the head two-elevenths. Brownish, mottled 

 with darker. 



This species has been recently discovered by Mr H. B. Jojiier at Tokei, and is intro- 

 duced here for comparison with the preceding species. The specimens collected are 9f 

 inches long.

D. 14, A. 14, V. 9. This gigantic species of Harpodon differs from Harpodon 

 nehereus in having a second distinct band of palatine teeth within the first one, and in 

 having the pectoral fin very short. The tubes of the lateral line are narrow and elongate ; 

 the basal half of the adipose fin is covered with scales. The interior of the mouth and 

 giU-cavity is black. 



A single specimen, 27 inches long, was obtained by Mr H. B. JojTier at Tokei. To 

 judge from the structure of its skeleton, and from its evident rarity, it seems to descend 

 to a moderate depth. 



Sahno macrostoma, n. sp. (PL XXXI. fig. A). 



B. 12, D. 13, A. 14, L. lat. ca. 130. This fish is distinguished by its remarkably 

 pointed snout, the upper jaw being rather the longer, and by its wide oblique mouth, 

 the narrow and sHghtly-curved maxillary extending considerably behind the hind margin 

 of the orbit. The head is small, only one-fourth of the total length (without caudal). 

 Eye small, nearly one-seventh of the length of the head. Teeth rather small ; one pair 

 on the head of the vomer is followed by three or four other small teeth, arranged in a 

 series. Prteoperculum crescent-shaped, without lower limb. Body rather deej:), its dcptli 

 being equal to the length of the Jiead. There are sixteen or seventeen scales in a serirs 

 obliquely descending from behind the adipose fin to the lateral line. Doi-sal fin but little 

 higher than long. Caudal fin deeply emarginate, silvery, wiih nine parr marks along the 

 lateral line, and with several round spots above and below thtni nn the sides. 



This fish is in many respects very similar to one figured by Brevoort in United States
