490 CONID^. 



chestnut or liver-colour. Examples do not usually measure 

 more than half an inch in length, and two lines in breadth. 



The animal is white, with flaky specks. Its tentacula 

 are closely set at their bases, very long for the genus, 

 subulate, with the eyes on bulgings very low down and 

 not far from their origin. The foot is lanceolate, trun- 

 cated, and acutely angulated with auricles in front. The 

 siphon is rather more attenuated than usual. Mr. Clark's 

 notice of this animal differs from our notes ; he resembles 

 it to that of gracilis. He states that the male organ is of 

 a pea-green colour. 



This is, in the main, a southern species, and rather 

 scarce. Dredged alive, and in peculiarly fine condition, at 

 Torbay, in from seven to ten fathoms ; also abundant at 

 Tenby, dead (S. H.) ; Exmouth, rare (Clark) ; Torquay 

 (Battersby); Bristol Channel (Jeffreys); Guernsey (E. F.). 

 In eighteen fathoms, mud, Hebrides (M 'Andrew and 

 E. F.) ; Oban (Barlee). On each side of Ireland, but 

 extremely sparingly (W. Thompson) ; Bantry (Jeffreys) ; 

 Cork Harbour (Humphreys). 



It ranges to the Mediterranean. 



The following sraull Fusi in Brown's " Illustrations," apparently belong to 

 this genus, but have baffled alike our own attempts at identification, and those of 

 our scientific correspondents. 

 F. multilinearis (p. 6, pi. 5, f. 22, 23) approaches aticnuata, Smithii, and costata, 



but has its outer lip dentated within as in purpurea. 

 F. crassus (p. 7, pi. 5, f. 8, 9) is possibly a nebula, judging from the assigned 

 number of its ribs, not from the figure, which might pass for a worn 

 attenuata with its beak broken off, or else for costata, 

 F./usciatus (p. 6, pi. 5, f. 41, 42) reminds one a little o{ striolata, but is stated to 



have fifteen ribs. 

 F. minutus (p. 8, pi. 5, f. 18, 24) is clearly the fry of a larger shell. 

 F. piunctatus (p. 7, pi. 5, f. 56, B7), possibly a young worn purpurea.
