Belfast (0. C), Dublin, Cork (C. C. S., J. V. T.), Galway (A. G. M.), 

 Roundstono IW. M'C.) 



Pagurtis lavis. — What I take to be this species has oecurred to me 

 both in Dalkey and also at Bray ; it differs from P. Ilyndmanni chiefly 

 in the comparative length of chelce. 



Portaferry (W. T.), DubUn (?), Galway (A. G. M.) 



Galathea nexa. — A small species, which I take to be this, occurs 

 pretty plentifully in Dalkey Sound and Bray, in 12-30 fathoms; it 

 spawns in March, April, and May. 



As contrasted with Galathea squamiferay the following points call 

 for notice : — 



Rostrum short, furnished with four flattened, hollowed teeth on 

 each side ; the hindmost pair situated on the orbit. (In Gal. squa- 

 miferay five spines, the hindmost two as G. nexa). Anterior pair of legs 

 narrowed, elongate, covered with a few tubercles, terminating, for the 

 most part, in a single spine ; some, however, pass into denticulate squa- 

 ma) : these tubercles are arranged on the hands in nearly parallel longi- 

 tudinal lineSy contrasting with the densely squamiferous anterior limbs 

 of G. squamifera. The hands are narrow and elongate^ the fingers nearly 

 parallel^ finely denticulate, scarcely hairy, terminating in a fine nail ; 

 they are slightly spinous on the exterior. External foot-jaws, second 

 joint equalling third. The description of G. nexa, in Bell, is so suc- 

 cinct that I am not quite sure whether this may not be a nondescript 

 species. 



Antrim (W. T.), Dublin (?) 



Falinurm vulgaris. — Although rare, there can be no doubt this spe- 

 cies has occurred in Dalkey Sound, and of large size. 



Astacus fiuviafilis. — Once, at least, in Bray River ; common in 

 streams about Maynooth, and also formerly taken in the Liffey. I have 

 seen specimens from the following counties : — Longford, Cavan, Tippe- 

 rary, Kildare, Dublin, Kilkenny; Meath. It is probably to be found 

 nearly all through Ireland. 



Crangon fasciatus Of this rare species I met with specimens at 



Sandycove, in the sandy pools, in a zostera bank at extreme low water. 

 Spawns in May. Every one of my specimens shows the broad black 

 band most distinctly. 



Dublin^ Bray (R. B.), Galway (A. G. M.) 



Uippolyte va/rians. — This species occurs in great numbers in the 

 sand-pools among the zostera banks at Sandycove, near Kingstown; 

 spawns in May. The specimens vary remarkably and beautifully in 

 colour : pink, red, saimon, emerald-green, cobalt-blue, gray, chocolate- 

 brown, opal white, are among the prevailing tints ; the ova of a choco- 

 late brown. 



It is remarkably sensitive of handling ; in no case could I succeed 

 in keeping it for over forty-eight hours in a tank, although specimens 

 of Crangon fasciatus and My sis chameleon, from the same locality, lived 

 with me for days. A volume might be written on the forms of the beak
