are still only 5 series of abactinal spines, but the adradial 

 series is very irregular, so that the broad space between the 

 medioradial series and the superomarginals, bears relatively 

 few and considerably scattered spines ; there are two series 

 of actinolateral plates and spines which extend more than 

 three-fourths of the arm-length, and the plates of the inner 

 series often bear 2 spines ; the inferomarginal spines are 

 very conspicuous, 5-7 mm. long and 2 mm. wide at tip, thick, 

 heavy and deeply grooved on the actinal side at tip ; the 

 characteristic large, slender pedicellarise are exceedingly 

 abundant, especially along the ambulacral furrows and about 

 the mouth. The small specimens (dry) are brownish-yellow, 

 but the largest (dry) is dull purplish-gray abactinally with 

 a decided red tinge, that suggests the possible natural colour. 

 Thirteen specimens.

This species was described from a specimen in Paris, re- 

 ported to have come from ChiH. Sladen, in the " Challenger " 

 Report, listed a specimen, without comment, from the reefs 

 at Kandavu, Fiji ! Now comes this third specimen from 

 Tasmania ! So far as I can judge from Perrier's description 

 and Sladen's " key," the fine, large ll-rayed individual, 

 figured herewith, represents C. gemmifera but I do not beHeve 

 the differences between Perrier's species and Gray's C. cala- 

 muria are worth much. If C. gemmifera really occurs in 

 Chili and Fiji and C. Calamaria really is found at Mauritius 

 (as reported), we have a very notable case of distribution, 

 which deserves critical study.
