species the name is giveu under which it appears in the classic mono- 

 graph of Alder and Hancock (referred to as A. & H.), hy means of 

 which the determination of species was almost entirely effected. For 

 distribution, jSTorman's Revision of the British MoUusca (Ann. Mag. 

 ISTat. Hist., series 6, vi., 1890) has been relied on largely, while the 

 records of Garstang for the Plymouth district, published in various 

 f aunistic papers in the Journal of the Marine Bi ological Association, 

 and of Herdman for the Irish Sea (Trans. Liverpool Biol. Soc. ; Sum- 

 mary in Annual Report, Brit. Assoc, 1896, p. 446), are referred to 

 under their names.

A large specimen, with the green and red colouring of Alder 

 and Hancock's drawing, was found by Miss Maud Delap in a 

 rock-pool at Reenagiveen. Small examples, averaging about 

 12 mm. in length, were commonly dredged in various parts of 

 the harbour, and one was found between tide-marks at Dohilla. 

 In these small individuals and in similar ones which are 

 common in parts of Plymouth Sound, the papillae exhibit no 

 green colour, the hepatic coeca being fawn colour or pale 

 brown, and the outer parts usually red and freely speckled 

 with opaque white. There is thus a decided superficial resem- 

 blance to Alder and Hancock's drawing of JEolis angulata, but 

 our specimens invariably have very numerous papillae, the 

 more anterior rows of which are sub-divided laterally, a cha-
