range of variation of slugs are by no means inconsiderable. Mr. 

 Renton sent me a few specimens of Limax arborum (the tree- 

 slug), and several of L. maximas, var. vulgaris. This, which is 

 the typical form of the species, is characterised as being black- 

 spotted on the shield, and having four longitudinal black stripes 

 on the body. To this character the smaller specimens sent by 

 Mr. Renton conform, but the large ones differ, inasmuch as the 

 body stripes are not black, but merely dark cinereons. There 

 were a large number of Limax agrestis sent, which ranged them- 

 selves into four forms, all equally common, viz. : — The type form, 

 as understood and defined in Lessona and Pollonera's excellent 

 " Monografia dei Limacidi Italiani " (cinereus immaculatus), and 

 the varieties reticulata, tristis and sylvatica, all of which may be 

 regarded as common in Berwickshire, and no doubt elsewhere as 

 well. The consignment also included several specimens of Arioti- 

 ater, which exhibited slight variations, not of any very great im- 

 portance. Out of seven sent, five were full grown, and had dark- 

 coloured feet ; while the two immature specimens had their feet 

 dirty-white. One of these last had the foot-fringe quite black, 

 while in the other it was dull buff marked with transverse black 

 streaks. With the slugs Mr. Renton sent specimens of Vitrina 

 pellucida, Zonites cellarius, Limncea peregra, Physa hypnorum, 

 Sphcerium corneum, Pisidium pusillum, Helix nemoralis, and 

 H. Horteusis, as a contribution towards the working out of a 

 county list of mollusca. 



I may perhaps be permitted to ask Scottish conchologists (or 

 naturalists generally) to help me in working out the variation and 

 geographical range of the British slugs. To this end I wish to 

 have specimens of all, especially the common species, from every 

 county in the British Isles, and in the case of some of the larger 

 counties which are divided for the purpose of botanical and chrono- 

 logical geography (see Watson's Topographical Botany) from each 

 of their divisions. The divided Scottish counties are Sutherland 

 (north-west and south-east), Ross (east and west), Argyle (Cantire 

 split off), Inverness (E. and W.), Aberdeen (N. and S.), and 

 Perth (East, Mid, and West). Specimens of slugs should be sent 

 alive, in a close-fitting, air-tight tin box.

THE ANGEL PISH, OR MONK PISH, IN LOOH KYAN. 



A good specimen of this strange-looking fish was recently taken in a salmon 

 net in Loch Ryan. So far as I could learn, it had not previously been seen 

 by any of the fishermen here. I had not seen it before, but had no difficulty 

 in identifying it from the drawing and description given by Mr. F. Buckland 

 in his " Familiar History of British Fishes." It is there named Squalus 

 squatina, Squatina angelus, or Squatina vulgaris. Mr. B. says, " It is by no 

 means rare on our coasts, especially in the northern parts of the kingdom," 

 thus differing from the statement of Couch. I think it must be considered a 

 somewhat rare fish. T. Barty.
