Micyosclcres. — 



(i.) Larger chelae, is-igji long. Usually their "palms" 

 as seen in profile, are parallel to the shaft or slightlv 

 deflected inwards. 

 (ii.) Contort chehe, 7-10 //. 

 (iii.) Toxa: observed 

 lengths, 45-370 fi. 

 This variety agrees with the 

 typical in possessing cla\ate 

 aranthostyli, but no mention of 

 tylostylote smooth spicules in 

 the latter occurs in Carter's 

 description.

 \\ hilst the agreement between 

 this variety and the preceding — 

 \ ar. s^eniiniis — is not so perfect 

 that one can with certainty 

 assert their identity, yet it has 

 been found Impossible to estab- 

 lish any wholly satisfactorv 

 points of difference. Seeing, 

 however, that the present sponge 

 has already been described as a 

 distinct species and is accord- 

 ingly already in possession of a 

 name, and since, moreover, it is 

 known only from a localitv 

 widely distant from that of the 

 other, no objection can be raised 

 if, for the present, and until 

 more and better material from 

 various localities is available it 

 is retained as an independent 



variety. The material which I -0 -• - .»». ^,cui^yi
