not to be rare in autumn and winter. Immature shells are not always 

 easy to distinguish from Hy. cellaria, but the dark blue animal of 

 Hy. Draparnaudi, with its equally dark footsole need never be 

 mistaken for the other species, whose footsole is always white. It 

 was also found to occur at Cushendun. 



Hyalinia crystal Una, Mliller. — The contracta form occurred with the 

 type at Murlough. 



Hyalinia fulva, Mliller. — The variety iI/^;Yt?«/ (J<^ff-) was found in the 

 sand drift in Whitepark Bay. 



Arion ater, L. — Very beautiful and varied forms of this slug occur in 

 Ireland. Of all the varietal forms, brunnea (Roeb.) is far the 

 commonest. At Murlough the forms phitnbea (Roeb.) and reticulata 

 (Roeb.) were also met with, and at Cushendun var. Szvammerdatnii 

 (Kal.) was found. Besides these well-marked forms various grada- 

 tions of colour impossible to separate by varietal names were 

 plentiful. A tolerably large album might be filled with representa- 

 tions of the various combinations and shades of colour which this 

 species assumes ; and this method is, I fancy, the only way to 

 preserve correctly the colours of slugs satisfactorily. Specimens of 

 the type and of the var. brunnea were found at Loughaveema, 900 feet 

 above the sea, in the midst of an extensive waste of moorland and 

 peat bog. Young specimens of this species, of which we found 

 plenty, were, like the English ones, all destitute of bands. 



Arion subfuscuSy Drap. — Though only three specimens seem to have 

 been noticed at Murlough last September, this slug is extremely 

 abundant all along the north coast of Antrim. In places the beauti- 

 ful brilliant orange var. aurantiaca (Loc.) is far more common than 

 the type. One specimen (type) was found at Loughaveema, 900 ft. 

 above the sea, with several of the last species. 



Arion hortensiSy F'er. — Two pretty forms of this common species 

 were obtained, viz., nigra (Moq.) in a wood near Ballycastle, and var. 

 stibfusca (C. Pfr.) at Murlough. 



Arion circumscrlptus, Jolnist. — Common at all the places visited. 



Arion intermcdius, Normand. — This proved common everywhere. 



Llmax nriaximus, L. — Of this handsome species only one small example 

 of the type occurred at Murlough, the var. Firussaci (^'lo(\.') everywhere 

 supplanting it. 



Llmax marginatus, Mullen [=Z. arborum^ Br. Ch.]— The pale watery- 

 looking form is that usually met with in north Ireland, but var. 

 Bettonii (Sord.) is commonly distributed, and in a wood at Ballycastle a 

 beautifully dark striped tawny individual (af ad. var. /«/z/a (Norm.) 

 was obtained. 



Agrioiimax agrestis, L. was in evidence everywhere, the purple var 

 sylvatica (INIoq.) being also abundant. 



Amalia Sowerbyi » Vkx — This appeared only on the mainland, at Cush- 

 endun, where it was common. According to Dr. Scharff's "Irish 

 I*, and B\ W. Moll." it is local in Ulster.
