Ancula cristata (Alder). — Redcar, "common, east end of West 

 Scar" (D.F.); Scarborough. 



Otina Otis (Turton). — Redcar, occasionally found on West Scar 

 (D.F.); Scarborough (Bean). 



Leuconia bidentata (Montagu). — Teesmouth (D.F.); Scar- 

 borough (Bean); rare in shellsand, Scarborough. 



Alexia denticulata Montagu. — Middlesbrough (Dixon & Wat- 

 son); Scarborough (Bean). 



Sthenoteuthis pteropus (Steenslrup). — Redcar, 1907 {Natura- 

 list, April, 1908); Gristhorpe. 



LoligO forbesi Steenstrup. — Off Staithes (Veitch); Scarborougli 

 (Bean); brought into Scarborough harbour for sale for bait. It is 

 caught in large numbers a few miles off; very rarely portions of the 

 pen may be picked up on the shore. 



LoligO media (Linne). — Scarborough (Bean). 



Sepia officinalis Linne. — Scarborough (Bean); at long intervals 

 considerable numbers of the bones are cast up on the shore at 

 Scarborough. 



Sepiola scandica Steenstrup. — Scarborough (Bean). Occasion- 

 ally alive at Scarborough and Filey. It is very aptly described in 

 Jeffreys' Brit. Conch, as squatting like a frog. I have seen it discharge 

 its ink, which mixed very slightly with the water as it rose to the surface 

 in a kii-d of bubble. The discharge would be of no use for con- 

 cealment. 



Sepiola atlantica d'Orbigny. — Coast to Dogger, sometimes as 

 food for dabs and gray gurnard (M.B.A.). 



Rossia macrosoma (delle Chiaje).^ — Off the Tees, 40-60 fathoms 

 (M.B.A.). 



Moschites cirrosa (Lamarck). — Living specimens occasionally 

 to be had in the North Bay, Scarborough, and fresh specimens 

 thrown up on the rocks. 



Gwynia capsula (Jeffreys). — Four miles off Robin Hood's Bay, 

 30-35 fathoms (Brady).
