Family.—_NYMPHONIDZ. 
Genus.—Nympnon, Fab. 
Nymphon gracile, Leach (Johnst.). 
This species has been found in Dublin Bay by Mr. W. F. de 
V. Kane, and in Queenstown Harbour by Professor Haddon. 
It is also recorded from the shores of Antrim and Down by 
Thompson. As it is described and figured very clearly by 
Johnston (3), there can be little doubt that Thompson’s determi- 
nation may be accepted, and that this form may be presumed to 
have a wide range around our coasts. Beyond the British Isles 
it is known from the south coast of Norway and the shores of 
Denmark and Holland; and Schimkéwitsch (2) has recently 
recorded it from the coast of South America, off Cape Vergini, 
where a single specimen was found by the “ Vettor Pisani.” It 
frequents shallow water. 
Nymphon rubrum, Hodge. 
At present, this species is known in Irish waters, only from 
Dublin Bay and Dalkey Sound, where Professor Haddon dredged 
several individuals of both sexes in 1882. A single female was 
also secured off Dalkey Isiand, in September, 1892, by the Dublin 
Naturalists’ Field Club. Except in the British seas, it has only 
been found on the southern coast of Norway (7). 
Nymphon gallicum, Hoek. 
This fine species, which was described by Hoek (4), from the 
zoast of Brittany, is not recorded for any other locality than the 
west coast of Ireland. An adult male taken by Miss A. Warren, 
in April, 1892, on the shores of Killala Bay, was noted by me in 
the Irish Naturalist (vol. 1. p. 168). The species has also been 
found at Broadstone by Mr. A. G. More, and at Broadhaven by 
Professor Haddon. It was dredged by the “ Fingal” in Brandon 
Bay (St. 18), at a depth of from 9-16 fms. on a sandy bottom, 
and by the “‘ Harlequin” (St. 160) in Boftin Harbour, at a depth 
of 1 or 2 fms., among sand and weeds. Quite recently I have 
received specimens from Mr. A. R. C. Newburgh, from the shores 
of Bantry Bay, taken at low-water mark. This, like WV. gracile, 
appears to be a shallow-water species.
