and Atlantic off Ireland 420-1380^ ('Porcupine'); S. W. Ireland 

 (R. I. A. cruise). 



My note on Cryptaxis crebripundahis Jeff., in the Journal of 

 Conchology for 1893 (p. 264) was meant to indicate its occurrence 

 in the Shetland-Faroe Channel, and not to introduce it as a British 

 shell, there being up to the present no record of its being found in 

 the British seas. The generic name is preoccupied, and will have to 

 be altered. Four unidentified species of this peculiar genus were 

 dredged by the ' Porcupine ' off the coast of Portugal in 1,095 fathoms. 



Philine Asc. — It is remarkable that all the members of this genus 

 are very rare in the Channel Islands, and altogether absent from 

 Jersey except an occasional P. aperta. Most of the species of Philine 

 have varietal forms marked with a diaphanous band round the 

 periphery. Besides such British varieties as are recorded here, I 

 have observed it also in P. intricata Monts. and P. striatula Jeff. 



P. scabra Miill. — Low-water mark in places to 95 fathoms. 

 Scilly Islands (Smart and others) ; Mayo and Sligo (Miss Warren) ! 

 Sutherlandshire, from haddocks (Baillie) ! Borough Island in S. 

 Devon ; West Orkneys. Belfast deposits (Prager) ! 



var. circa Marsh., Journ. of Conch., 1889, vol. vi., p. 57. — Scilly 

 Islands (Burkill and J.T.M.); Killala Bay; Arran 25f 



Crag specimens are very much larger than recent ones, and measure 

 " axis half an inch " (S. Wood). An oval form occurs at Arran, some 

 specimens of which have the aperture projecting beyond the spire. 

 Another form frequently occurs which is smaller, shorter, squarer, 

 and more open or patulous. 



P. catena Mont. — Low-water to 45 fathoms. Scilly Islands 

 (Burkill and J.T.M.); Mayo and Sligo (Miss Warren)! Guernsey 

 2of., rare ; Torbay, in rock-pools at low spring tides ; Doggerbank 

 25-4of, Connemara, Portrush, Cumbrae i8f., Minch off Barra 33f., 

 Benbecula Sound lof , West Orkneys 45 f. 



var. zona Jeff. — Mayo and Sligo (Miss Warren)! Guernsey, Land's 

 End^ Torbay, Caldy Island, Tenby, and Dornoch Frith. A^ot more 

 depressed than the type. 



This species appears to thrive and to be most plentiful from the 

 Land's End to South Devon ; it is diffused throughout the Hebrides, 

 but sparingly. My largest are from S. Devon, and measure two lines 

 by one, though two specimens from Gairloch are 2i- lines by i|. The 

 sculpture is similar to the last species, but much finer. Jeffreys' 

 figure is a bad one ; it exhibits no sculpture, the pillar is too large, 

 and the crown too narrow; Sowerby's is better, though the upper 

 angle of the aperture is too high, and the base should be somewhat 

 square instead of obtusely pointed.
