264 MARSHALL: ADDITIONS TO ' BRITISH CONCHOLOGY.' 



ovata has sometimes been confused. C. striatula is a 

 conical shell with a truncated apex, has spiral strise at the 

 base, and longitudinal striae at the apex, and is more solid. 

 (See also 'Annals' for July, 1870). 



Acera bullata var farrani Norman. The large Connemara 

 form dredged by Dr. Farran, mentioned in 'B.C.,' vol. iv., 

 p. 432, has been very appropriately named by Dr. Norman 

 ViXX. farrani. This and the var. nana he thinks should be 

 'regarded as entitled to rank as species'; but size has never 

 been considered by itself a specific character, and the range 

 in size of these two forms, though very great, is not excep- 

 tional. 



Scaphander punctostriatus Mighels. (See the 'Annals' for 

 July, 1890). This is the S. librarius of Loven and of 

 'British Conchology' ; but Mighels' name is prior. 



Cryptaxis crebripunctatus Jeff. A new genus and species 

 established by Jeffreys for several specimens of a small 

 Bulla taken in the 'Triton' cruise of 1882 between the 

 Hebrides and Faroes, in 570 fathoms. It was described 

 and figured by the author in Proc. Zool. Soc, June, 1883 ; 

 and Dr. Norman has some notes on it in the 'Annals' for 

 July, 1890. Jeffreys gives the dimensions of his largest 

 specimen as 2 lines by i ; but Mr. Jordan has a still larger 

 specimen from the Faroe Channel, measuring 2^ lines by i|-. 

 It is impossible to say if this is adult — it may be immature. 

 Mr. Jordan's specimen contains the animal, which I hope 

 he will some day describe. 



Philine scabra v. circa Marsh. (See'J. ofC for Apr. 1891). 



P. angulata var. circumlustra Marsh. Having a broad 

 clear band encircling the periphery. Jeffreys in his de- 

 scription says that ' occasionally one or two transparent 

 zones may be seen'; but I have never met with any devia- 

 tion from the one broad transparent band. I have this 

 from the Eddystone, 28 fathoms; Tenby, Portrush, Killala 

 Bay, and Sutherlandshire.
