and the anal beyond the median caudal rays; the external caudal rays increase, 

 and become twice as long aa the median, and the ventral extend backwards 

 nearly as far as the base of the anal. The pectorals are constant in their pro- 

 portion, and equal the length of the head exclusive of the operculum.

When dried, the color is brownish-yellow, and reticulated, the margin of 

 each scale being darker. The terminal halves of the posterior dorsal and anal 

 fins, as well as of the shorter caudal rays, are orange ; the largest caudal rays, 

 and the anterior borders of the dorsal and anal are reddish ; the rest of these 

 fins, as well as the ventrals, are darker. The pectorals are orange, with its tip 

 marked by a large dark spot. 



" When alive, a yellow patch of the size of a half dollar is just behind the 

 side (pectoral) fins. Head, tail, and all the fins bright red, with the tips black 

 and yellow. Whole body bright blue." 



It is allied to Harpe rufus Cossyphus ?/; Gthr., or Cossyphus bodianus Cuv. 



There are three specimens in the collection: 



1st. One a foot long from the snout to the concavity of the caudal, beyond 

 which the external rays project about an inch ; the dorsal extends little beyond 

 the scaly sheath of the caudal, and the anal to the middle of the external rays ; 

 the ventrals reach the anal. The forehead is not gibbous. 



2d. One sixteen inches long to the concavity of the caudal fin, of which the 

 exposed parts of the external rays are twice as long as those of the others ; the 

 dorsal extends backward nearly to, and the anal beyond the caudal margin; 

 the ventrals pass the middle of the base of the anal. The hump of the fore- 

 head exceeds by a half the eye's diameter. 



3d. An old specimen, two feet long, with the caudal lobes rather more pro- 

 duced, but the dorsal, anal and ventrals rather less than in the second. The 

 hump on the forehead is very elevated, and twice the diameter of the eye.

Genus JULIS (Cuv.) Giinther.* 



JULIS LUCASANCS Gill. 



The height at its highest part equals a fifth (19-20) of the total length. 

 The head is oblong, moderately decurved in front of the eyes, and forms nearly 

 a quarter of the total length ; its height above the preopercular margin nearly 

 equals two thirds (15-24) of its own length, and over the pupil, a half (12-24). 

 The length of the snout equals a third and is about twice as great as the 

 height of the pieorbital. The diameter of the eye equals a quarter of the 

 head's length. The interorbital area is nearly arched transversely, and its 

 shortest width exceeds the diameter of the orbit. 



The dorsal fin commences nearly over the bases of the ventral fins, and is 



* The Julis modeling of Ciirard (Halichceres cali/ortiicus Gther) belongs to this genus. 

 The discnption by (iirard of ihis species, as well as most oihers, is very defective, the 

 churacters being chiefly vague or generic. 'J lie Julis modestus has an oblong, acutely

1 have not seen the Julis semic'nctus of Ayres, bui on account of its height and the 

 presence of nine dorsal spines, am inclined to refer it to Hulichreres, or rather V/iceroju/is, 

 the former name being preoccupied for a genus of Seals. Ayres, like Girard, may have 

 mistaken the number of ypines, but it may be assumed ihat he is correct.
