i899-] Scharff & Carpenter. — Animals from the Reeks. 215 



This slug is so much like Agriolimax agiestis in general 

 appearance (except colour), that we at first sight naturally 

 mistook it for an Agiiolimax. Examination of the repro- 

 ductive organs showed however a close correspondence with 

 Limax marginatus, while Professor Simroth (to whom a speci- 

 men was sent) drew attention to another limacine character — 

 the six convolutions of the intestine ; Agriolimax has only four. 

 Indeed the internal organs of this slug from the Reeks agree 

 in all respects except size with those of an ordinary Limax 

 marginatus, which is generally double the size of the present 

 variety. 



Limax marginatns (formerly known as L. arborum), has a 

 very wide range in Europe, but it is more common and variable 

 in the west than in the east One of us has taken it as far south 

 as the Canaries, and it is recorded fro-m Scandinavia, the Faroes, 

 and the Shetlands. The beautiful variety maculata, described 

 by Roebuck, and recorded by him from Co. Mayo, seems to 

 be confined to western Ireland ; iii the south-west it has been 

 noticed only around Killarney and Berehaven. The present 

 form (var. ?iiger) occurs, according to Professor Simroth, also 

 in Transylvania. It approaches very closely var. rupicola of 

 Lessona and Pollinera, which occurs in the Piedmontese Alps 

 up to 7,000 feet, and has been recorded by Roebuck from the 

 Mourne Mountains, but differs from that form in being 

 entirely unicolorous above. Other varieties {Betto?iii and 

 7iemorosa) are also known from Ireland. 



Besides this interesting slug, Arion ater (the blajk variety 

 only) A. subfuscus (a small dark brown form) and A. i}i(cnnedius 

 were found sparingly above 2,700 feet. At that height 

 Hyaliyiia alliaria occurred, but no snails were noticed beyond. 

 The flies Tipula hortensis and Sepsis cynipsea and the spiders 

 Bathyphantes varicgatus, Leptyphantes Blackzuallii, L. te?iuis, 

 and Textrix de?itieulata were noticed up to 2,500 feet, but not 

 higher. Other species however were to be found right up to the 

 summit of Caher : — Tapi?wpa longidens, Porrhomma pygmcea, 

 Tmeticus prudefis, T. Hitthwaitii, T. abnotmis, T. bicolor var. 

 co?ici?mus, and W 'alckaiacra nudipalpis. Of the mountain 

 beetles, Carabus catenulatus occurred as high as 2,700 feet, while 

 from that level up to the summit of Caher we met with Leistus
