 than the eye ; eyes of moderate size, with round pupil, rather distant ; 

 a fold in front and behind the orbit. Inner nostrils and eustachian 

 openings small ; lower jaw without prominences ; tongue longish, 

 deeply nicked behind. Body and limbs rather stout ; back and sides 

 with numerous large, smooth glands ; belly smooth ; an indistinct 

 cross fold between the fore legs. The fore leg, if laid backwards, 

 does not extend to the vent ; fingers and toes tapering ; the first and 

 third fingers are equal in length, and longer than the second and 

 fourth. Hind legs much longer than the body ; toes two-thirds 

 webbed, the third a little longer than the fifth. Dark-greyish olive, 

 marbled with darker ; an indistinct hght streak between the eyes.

 Port Natal. 



Centropogon marmoratus.

The third to sixth dorsal spines are the longest, half as long as 

 the head ; the second anal spine longer and stronger than the third. 

 Yellowish, marbled with brown.

Description. — This species is similar to Centropogon australis, 

 from which it will be readily distinguished by the shorter third dorsal 

 spine, which in C. australis is two-thirds as long as the head. The 

 height of the body is contained thrice and a half in the total length ; 

 the length of the head thrice and a quarter. Head slightly com- 

 pressed, with deep grooves along the interorbital space, which is 

 concave and much narroAver than the orbit ; there is a slight groove 

 behind the orbits, across the occiput. Snout shorter than the eye, 

 the diameter of which is scarcely more than one-third of the length 

 of the head. Cleft of the mouth slightly oblique, of moderate width, 

 the maxillary extending beyond the front margin of the orbit ; jaws 

 equal in length anteriorly. Each turl)inal bone with an obtuse spine 

 superiorly; prseorbital spine strong; prseoperculum with five spines, 

 the upper of which is the longest ; operculum with two ridges ; 

 spines on the occiput small and obtuse. Head naked, without cu- 

 taneous appendages ; vomerine teeth in a narrow angular band. 



The dorsal fin commences immediately behind the occiput, its 

 spines are of moderate length and strength ; the third to the sixth 

 are the longest, half as long as the head ; the following decrease in 

 length, the last, again, being a little longer than the penultimate ; the 

 soft dorsal rather more elevated than the spinous, short, the length 

 of its base being contained thrice and a fifth in that of the spinous
