fish, Acaiilhias vulgaris, which did great damage to the drift-nets of the 

 fishermen and scared the salmon from the nets. These fish moved about in 

 large shoals, and wherever they encouutered the nets quite filled them. 

 Indeed I was told of one catch filling three large yawls, and on July 17th I 

 saw one boat come in with over a ton weight of Dogfish on board, but amongst 

 this large boat-load I saw only two of the small spotted species, Scylllum 

 canicula. They had evidently visited the shoal water of the Cay for the 

 purpose of bringing forth their young, which were quite ready for exclusion, 

 many actually producing their young on being taken on board the boats. 

 There was a similar visitation of this species of Dogfish to our Bay and the 

 adjacent coast in the summer of 1882, when they did so much damage to 

 the net and line fishermen that fishing was entirely stopped until they had 

 left the Bay for deep water. — Robert Warren (Moyview, Balliua). 



[For the benefit of those of our readers who may not be familiar with 

 this fish, we may remark that it is one of the commonest of the Sharks 

 (Spinacida) which frequent our coasts. The name " Picked Dogfish " is 

 evidently a corruption of " Piked Dogfish," so called from the two sharp 

 " pikes " or spines which it carries on its back in front of each dorsal fin. 

 Its predatory habits are well known to the fishermen, and the herring and 

 pilchard fisheries are often seriously affected and depreciated by the attacks 

 made upon them while in the nets, which are often much damaged in 

 consequence. Some interesting statistics upon this subject will be found 

 in Day's 'Fishes of Great Britain and Ireland,' vol. ii., pp. 316,317, 

 where a good figure of the fish is also given. — Ed.

Dromia vulgaris on the Sussex Coast. — I have a specimen of this 

 Crab which was sent me alive in May, 1886. It was obtaiued by scallop- 

 dredgers in the channel off Newhaven, or Beachy Head. — William 

 Jeffery (Katham, near Chichester).
