(The Globe.) 



My specimen agrees very well with Dr. Gkmther's excellent 

 description of this sort, but the spines are all about of equal 

 length, and rather short ; the posterior, if any, being the longest. 

 I find the dorsal large, formed of sixteen rays ; the caudal 

 rounded posteriorly, of nine rays ; the anal is much smaller than 

 the dorsal, but is not complete in my specimen, and I only see the 

 roots of six rays ; the pectorals have twenty rays. 



The colour is of a light green on the upper part, and white 

 below ; all the spines are white, but those of the back have a 

 black rounded spot at their base ; the fins are s of a yellowish 

 green, with the end of the dorsal and caudal darker; the 

 anal is white ; the eye was, on the living specimen, of a dark 

 brown, with an internal yellow circle. This fish, when inflated, 

 forms a perfect globe. 



The specimen is four and a-half inches long. Erom Hobson's 

 Bay The air-bladder is large, rounded, and strongly bifur- 

 cated. 



Group MOLINA. 



Body compressed, very short, not extensible by air ; tail extremely 

 short, truncate, vertical ; fins confluent ; no pelvic bone ; air- 

 bladder absent. 



ORTHAGORISCTTS.

 considered by Dr. G-unther and Professor M'Coy as belonging to 

 the European sort. The first also includes with Orthagoriscus 

 Mola the sort described by me at the Cape of Grood Hope under the 

 name of Pedalion Capensis. He states that the remarkable nose-
