Scilly and Land's End. The southern species, Nika edulis, Kisso, 

 is rarely found in Plymouth Sound, but is sometimes moderately 

 common in Cawsand Bay, and is occasionally obtained in 20 to 

 30 fathoms outside (M. B. A.) It has been dredged in from 8 to 15 

 fathoms in Whitsand Bay East, once obtained in shallow water 

 near Polkerris Harbour, Tywardreath, and twice in berry near 

 Mevagissey in February. It is at times fairly common in fine 

 sand in 30 fathoms about four miles east of Nare Point, and 

 has been occasionally identified in trawl-refuse from the south of 

 Gull Bock, Porthscatho, and once from the Wolf. The type 

 specimen of Nika couchii, Bell, was obtained by Couch off the 

 north coast of Cornwall. It has also been captured by Spence 

 Bate in 30 fathoms, but has apparently not been seen by any 

 other naturalist. Cheraphilus trispinosus (Hailstone) is plenti- 

 ful locally on a bottom of fine sand in 3 to 8 fathoms along the 

 south coast to Mount's Bay and at Scilly, except on much 

 exposed parts of the coast. In Cawsand Bay (M. B. A.) and in 

 Whitsand Bay East it is patchily common. At Fowey it is at 

 times plentiful in 4 fathoms. In Mevagissey waters it is of fre- 

 quent occurrence, and it is sometimes taken in fair quantity 

 with the rake- dredge in Falmouth Bay and in Mount's Bay. 

 On July 8th, 1908, several specimens were captured on 

 the Great Western Beach at Newquay, and on August 11th, 

 1904, it was abundant in Crow Sound, Scilly, in 3 to 4 

 fathoms, between Guthers and Innesidgen. Females occur in 

 berry from April to August. Cheraphilus nanus (Kroyer) was 

 captured on the surface in Plymouth Sound in February, 

 1887, and recorded by Cocks from trawl-refuse, and as having 

 been taken by Dr. Vigurs at Bar Point, Falmouth Bay. In 

 July, 1890, an immature specimen was obtained at Zennor, and 

 afterwards identified by Dr. A. Milne-Edwards. Pontophilus 

 spinosus, Leach, is of frequent occurrence locally on sand and 

 gravel in deep water along the south, but nowhere common. It 

 is found on the Rame-Eddy stone Grounds (M. B. A.) in 25 fathoms 

 south-east of Longstone Rock, Whitsand Bay, in 30 to 35 

 fathoms south of the Dodman, in trawl-refuse from 40 fathoms 

 3 to 5 miles south of the Gull Rock, Portscatho, and at a similar 

 depth 15 miles east of the Lizard. At Scilly it has been 

 obtained on sandy gravel about half a mile west of Shipman
