LIST OF SPECIES. 



Umax maximus L. — (T.)~Bur:iham woods, Gallerus, Cloghane, Strad- 

 bally, Castlegregory Junction, Dingle, Fermoyle and Kilcummin 

 woods, Finglass Gorge and Gt. Blasket. Apparently widely distributed 

 in the valleys, especially where woods occur or the remains of native 

 scrub lingers in the hedge -banks. The form which prevails throughout 

 the district is dissimilar from that which we find in the north-east of 

 Ireland. In the latter part of the country specimens are generally 

 spotted, but without distinct bands. In this district not only are 

 the bands distinct, but these are made more prominent by brilliant 

 darker spots, while the whole scheme of colouring is brighter. Mr. 

 Tomlin's specimens from Cloghane have been referred by Mr. 

 Roebuck to var. sylvatica, Morelet. 



L. cinereo-niger Wolf. — (T.) — Mr. Tomlin records the type and var. maura, 

 and states that he found young specimens of both " not uncommonly 

 on Brandon Mountain at an elevation of 2,500-3,000 feet." It is 

 curious that on my three visits to Brandon I have never been able to 

 find a trace of this slug, though examples of Arion ater and Limax 

 arborimi have always been abundant. Nor in other parts of the 

 promontory have I been more successful ; only on the Gt. Blasket did 

 it occur to me. Here two specimens of a rich chestnut-brown colour 

 w^ere taken. I have since discovered that this slug is born yellow, and 

 in reaching its adult colouring passes through a chestnut -coloured 

 stage at about the age of six to nine months. As one of the specimens 

 taken on the Gt. Blasket was fully grown and the other about 

 three-quarters grown, perhaps we have to deal here with a primitive 

 race of the species with adolescent colouring. 



[L. flavus L. —Found by Mr. Welch near Burnham House, at Dingle. No 

 doubt an artificial introduction.] 



L. arborum Bouch. -Chant. — (T.) — Abundant throughout the district to 

 the summit of Brandon Mt. 3,127 feet ; to 900 feet on the Great 

 Blasket. Two well-marked forms occur. One occupies the higher 

 ground, is small and often almost black, and has been identified by 

 Mr. Roebuck as var. rupicola, Less, and Poll. ; the second is confined 

 to the valleys, especially to the areas occupied by native scrub, is 

 very much larger and pale in colour, and considered to be typical of 

 the species by Mr. Roebuck. The latter form is usually associated 

 Avith L. inaximus. These two forms of L. arborum are so divergent 

 that I sent samples of both to Dr. A. E. Boycott, who reports that no 

 difference in their anatomy was to be observed. In no locality have 

 I seen these two forms associated. This species is not mentioned by 

 Mr. Tomlin as occurring on Brandon Mountain, which is more than 

 strange. 



Agriolimax agrestis (L.), — (T.)--Common throughout the district to 1,400 

 feet at Connor Hill, but noticeably absent from the higher ground- 

 Taken on both the Gt. Blasket and Beginish. Shows little variatioji 

 in colour from the type. 



A. laevis (Miiller). — (T.) — At 500-1,000 ft. on Carrigblagher cliffs, west of 

 Lough Anscaul ; Incli, rare ; CojT,nor Hill at 1,400 feet alt. ; in the
