Platycephalus longispinis. n. sp. 

 D. 1/7/14. A. 14. L. lat. 75. 



Somewhat like P. Basse7isis. Length of head 3J in the total 

 length, width of head one-fourth of the same. The space between 

 the eyes is flat and less than the diameter of the eye, with a 

 distinct ridge on each side commencing at the anterior edge of the 

 orbit, and terminating at the extremity of the occiput, the latter 

 part of the ridges interrupted, and resembling long, low, recumbent 

 spines, without being spinous. Another very low similarly in- 

 terrupted ridge is traceable behind the eye, commencing with one 

 or two short spines, and extending to the commencement of the 

 lateral line. A trace of another ridge in the median line of the 

 head is to be seen near the snout, and again behind the eyes in 

 about the line of the prseorbital spines, it shows in one very low, 

 long, recumbent spine. The prajocular terminates at its outer 

 anterior angle in a strong, acute, short spine, from thence proceed 

 two ridges, with a smooth groove between to the prseopercular 

 spines, the first sixth of the lower of these ridges is strongly 

 serrated The lower prseopercular spine is very long, strong, 

 acute, and grooved on its thicker portion, the upper is less than a 

 third of the length of the other, and points upwards and away from 

 it. One spine on the operculum. The lower jaw is longer than 

 the upper. 



Lateral line smooth. Coloration yellowish-grey, spotted with 

 yellow on the upper surface, white on the under surface, the two 

 dorsals and the pectoral fins spotted with brown ; the ventrals and 

 anal white. The caudal fin is imperfect in my only specimen, but 

 it seems to have been clouded with black. Length, 10 inches. 



Taken in a trawl net outside Port Jackson in 50 fathoms.
