Five of the examples of this species obtained by the 

 "Endeavour" (group A in table below) differ from the 

 rest of the Australian specimens which I have studied 

 (group B) in having generally a somewhat larger eye, 

 and fewer and shorter gill-rakers. Examination of 

 typical examples of P. arsius from East African and 

 Indian Seas (group C) shows that the number of gill- 

 rakers ranges from 8 to 13, and that the size of the 

 eye is variable, as in most Flatfishes. 



The specimens forming group A were taken in some- 

 what deeper water (19 to 35 fathoms) than those of 

 group B. They do not seem to present sufficient 

 differences to warrant their separation as a distinct 

 species or subspecies, and may be regarded as a race of 

 P. arsius. 



Teratorliombus excisiceps, Macleay, proves to be an 

 abnormal (ambicolorate) example of Pseudorhombus 

 arsius. Mr. McCulloch informed me that in this 

 specimen, and in another ambicolorate example preserved
