are pale, dirty grayish, or brown, and show no trace of any of 

 the original colours. Four specimens. 



Logs. — Off Fraser Island, Queensland, 32 fathoms. 



Twenty-five miles south-east of Double Island Point, 

 Queensland, 33 fathoms.

Although these specimens show considerable diversity in 

 proportions and in spinulation, in view of the well-known 

 inconstancy of characters in the genus, I do not feel justified 

 in recognising more than one species, and that one I, for the 

 present, identify with Perrier 's species from southern South 

 America. I cannot go as far as Ludwig and consider all the 

 Antarctic and sub-Antarctic Henricias as a single species, for 

 I doubt if Studer's H. pagenstecheri is identical with Perrier's 

 H. hyadesi, and I am quite prepared to learn that the Austrahan 

 and South American Henricias are distinct. But until more 

 material is available, it is futile to discuss the matter. It is 

 worthj'^ of note that all the Australian specimens are from 

 water relatively deep for the genus. The largest specimen 

 has R = 80 mm. ; in another R = 75 mm. ; br==18 mm. ; in 

 a third, R = 67 mm. ; br=9 mm. Usually the arms taper to 

 a slender tip, but in one specimen they are rather uniformly 

 stout. One specimen from the Great Austrahan Bight has 

 6 arms but does not seem to differ otherwise from the rest. 

 All the specimens have lost their original colours, and are now 

 some shade of yellowish-brown. Eleven specimens.
