9. cncEROPS. 95 



d. Half-grown. From Mr. Brandt's Collection. 



e. Half-grown : stuftcd. Cape York, in 63 fathoms, with hook and 



Une. Voyage of the ' llattlesnake.' 



Sir John Richardson has evidently confounded the measurements 

 of the typical specimens of this and other allied species. _^A specimen 

 65 inches in length does not exist in the British Museum CoUectiou. 



Cossi/jjhKS ci/anostolus, Eichards. Ichthyol. Chia. p. 256, is founded 

 on a mounted specimen, on two others in spirits, and, finally, on a 

 drawing of Mr. Beeves. The mounted specimen has evidently served 

 as the type not only of 0. ci/anostolus, but also of a second species (C. 

 ommoptenis), to which it properly belongs. Secondly, the two speci- 

 mens in spirits belong to a very different species, which is distin- 

 guished by a large pearl-coloured spot on the side of the body (CA. 

 oligacanilnis). Thus the species rests entirely on Mr. Reeves's drawing, 

 which is described by Sir J. Richardson ; that drawing shows only 

 twelve dorsal spines.

The single specimen observed is 44 mm. long, and is probably the 

 immature state of some other kncwn species, perhaps of Chcerops 

 ommopterus.
