collections to fall into the error of uniting the two species, but in all 

 the specimens which I obtained the coarse texture of the animal, and 

 the colour and texture of the foot, proves the distinctness of the animals ; 

 and specimens of H. nemoralis with white lips, obtained by me in 

 August on the Antrim road, Carrickfergus, confirm this observa- 

 vation. Among the specimens of IT. hortensis obtained were several of 

 the curious Albino variety, in which the glands of the mantle not se- 

 creting any colour, translucent bands pass along the whorls of the shells. 



An examination of the original specimen of Pagurus Dilwynii 

 (Spence Bate), in that gentleman's possession, enables me to point out 

 another distinction between this species and all the British Paguriform 

 Anomoura which I have had an opportunity of examining, viz., the form 

 of the scale at the base of the eye, which in sp. Bernhardus, Thotnpsoni, 

 lavis, Prideauxiiy Cuanemis, Hyndmanni, and Zflidianus, is invariably 

 entire along its outer edge, and the scales of opposite side divergent, 

 whilst in P. (?) Dilwynii these parts are triangular, strongly den- 

 ticulate along upper outer margin, the inner edges parallel, and closely 

 ;ipproximating, exactly as in many species of the genus Paguristes of 

 Dana. It evidently belongs to a distinct genus from the other species 

 of Paguroid Anomoura found on the British coasts. 



The following shows the species of Crustacea met with during my 

 visit ; it of course gives only an imperfect idea of the Crustacea of the 

 neighbourhood : —
