MK. MARTIN JACOBY ON NEW SrBCIES OP [DeC. 13, 



read before the Zoological Society, a paper has appeared on the 

 " Plymouth Marine Invertebrate Fauna " in the Journal of the 

 Marine Biological Association (n. s. vii. 2, Dec. 1904), in which 

 notes furnished by myself and Mr. Bidder are mixed up together 

 with rather contradictory results (p. 185). Thus Leucosolenia 

 hotryoides is stated to occur " on the shore between tide-marks, 

 not abundant except in certain localities (E. A. M.) ; rocks under 

 the Hoe, in abundance [G. P. B.)." L. variahilis is put doAvn as 

 "common- everywhere in rock -pools between tide-marks {E. 

 A.M.)." The fact is that Bidder has not TQcogn\s,edi variahilis 

 and hotryoides as distinct, and, taking the characters of hotryoides 

 from Bowerbank (whose figured specimen of this species was 

 really variahilis), Bidder has not unnaturally identified sponges 

 as hotryoides which should have been named variahilis. Bidder's 

 note on the occurrence of hotryoides should therefore be trans- 

 ferred to variahilis, and then it will be perfectly correct. The true 

 hotryoides is certainly very far from abundant on rocks under the 

 Hoe ; I doubt if it ever occurs there.]
