The height of the body is four times in the total length, the lengtli 

 of the head 3^ ; the distance betAvccn the eyes is 4i in the latter ; 

 the length of the snout is nearly equal to the diameter of the eye. 

 The upper processes of tlie intermaxillaries reach fur between the 

 eyes ; turbinal bone not covering the intermaxillary' ; lower jaAV 

 very prominent. Operculum -n-ith two distinct spines, the lower of 

 which is rather the smaller. Lobes of the caudal equal. The tliird 

 anal spine is 4|- in the total length. The spinous dorsal with a deep 

 black blotch between the first and fourth spines, and witli two series 

 of white spots, one along the upper margin, and the other alonj^ the 

 base.

Skeleton. — The general structure of the skeleton being the same 

 as in the preceding species, I give a detailed description of tho.se 

 parts only which exhibit specific peculiarities. Tlie fan-like ex- 

 pansion on the vertex is fonned by nine or more radiating branches. 

 The orbital edge of the frontals is concave, these bones fomiing 

 a slight prominence above the anterior part of the eye. The 

 groove for the posterior processes of the intermaxillaries reaches 

 far behind, nearly to the level of the second third of the eye. The 

 maxillary bone is styliform at its origin only, and then forms an 

 oblong plate with an irregularly convex anterior margin, and with 

 the posterior rather concave. The supplementary bone is composed 

 of two pieces, the posterior of which is larger and slightly denticu- 

 lated in front. The intermaxillaries are separated from one another 

 by a deep notch ; they arc three-quarters of the length of the 

 maxillary bones, and have a very prominent and flat protuberance 

 behind. The mandibularies arc distinguished by their length, con- 

 siderably overreaching the upper jaw.
