Leucothoe farina, Chevreux, Extrait du Bulletin de 

 la Societe d' etudes scientifiques de Paris, 11* an nee, 

 l*"" semestre, 1888, p. 9. — Norman, Ann. and Mag. Nat.

Habitat. — Balloch Bay, Cumbrae, at low water. 

 Dredged off Fairland Point, Cumbrae, in 20 fathoms. 



M. Chevreux was the first to publish any obser- 

 vation on the distinguishing feature of this species, 

 namely, that the hind margin of the third pleon- 

 segment is incised below, so that the angle forms 

 a kind of hook M. Chevreux supposed that this 

 feature had been overlooked by Spence Bate in his 

 account of Leucothoe furina (Savigny), but neither 

 the careful figure of Lycesta furina in Savigny's 

 Egyptian Crustacea, jDlate xi. fig 2, shows any trace 

 of the incision, nor is it found in those British 

 specimens of Leucothoe which most closely agree 

 with Savigny's species.
