RARITIES FROM THE YORKSHIRE COAST. 



( Reprinted from "Ashore or Afloat,' 1 for October $tk, 1883.J 



Callionymus Lyra, L., the Dragonet, is recorded in Clarke 

 and Roebuck's " Yorkshire Vertebrata " as " occasionally 

 taken off the coast in deep water, but not common." On the 

 13th of August I caught two specimens off Redcar with a 

 small trawl net, in four or five fathoms of water. I succeeded 

 in bringing one home alive, but the other died in transit. 

 What struck me as curious about this capture was the com- 

 paratively shallow water in which the fish were found. The 

 bottom was sandy, and in the same haul we obtained various 

 flatfish, the lesser weever, the grey gurnard, &c. Dr. Day 

 remarks, in his " Fishes of Great Britain and Ireland," that 

 the adult males of this species prefer deep water (twenty to 

 sixty fathoms), while the females and young are often found 

 nearer in shore, especially in sandy bays and in the mouths of 

 large rivers. This may account for my specimens being 

 found so near in shore. I think the one alive is a female, 

 though the dorsal fin is rather longer than figured by Dr. 

 Day, but not nearly so long as his figure of the male. My 

 specimen is six inches long, so this is probably an immature 

 form. 



Eolis Peachii, A. and H. I found one specimen of this 

 pretty little nudibranch on a shell inhabited by a hermit crab, 

 which was covered with zoophytes, polyzoa, &c, brought 

 from Redcar, August 7th, I883. It agrees with Alder and 

 Hancock's description, except that the dorsal tentacles are 

 about, if not quite, twice the length of the oral tentacles. 

 There appear to be only two species of Eolis which have the 

 head broader than any part of the foot, and these are E. peachii 

 and E. nana. In the former the oral tentacles originate from 

 the margin of the lip, in the latter they are placed rather far 

 back on the head. My specimen has the marginal oral ten- 

 tacles, so there appears little doubt as to its identity. Colour 

 differs a little from Alder and Hancock's description and 

 figures. (" Nudibranchiate Mollusca, Ray Socy.," plate 10.) 

 There is scarcely a trace of yellow in the general body tint, 

 and the gill cores are more olivaceous, with less of the red 

 tint. Length rather more than J inch. I might have con- 

 sidered this a young specimen with colour not fully developed, 

 but that it had laid a mass of ova irregularly placed in a 

 colourless mucus, much resembling Alder and Hancock's 

 figure for E. concinna. The yolks had a slight rosy tinge. 



Eolis exigua, A.andH. Found several specimens apparent- 

 ly belonging to this species among zoophytes (Obclia geniculata,
