LONGSTAFF : NON-MARINE MOLLUSCA OF MORTEHOE. 17 



Limax maximus Linnd— Not frequent. Wall of church; 

 Twitchen garden and wood. 



var. fasciata Moquin-Tandon.— Twitchen, on a tree in the 

 wood. Identified by J. W. Taylor, and stated by him to be "much 

 redder than usual." 



var. miilleri Moquin-Tandon. — ^Twitchen, two specimens under 

 stones, one remarkably fine. Identified by W. Denison Roebuck. 



Limax cinereo-niger Wolf var. ornata Lessona. — Borough 

 Wood. Confirmed by Mr. Taylor. Two specimens under logs. 

 One large, nearly black, keel greyish-white, with a row of elongated 

 grey spots on each side, and indications of a second row near tlie 

 shield. The other specimen is smaller, has a brownish tinge, and 

 two complete rows of spots on each side of the keel. This seems 

 to be the first recorded instance of the species being found in Devon- 

 shire. Also another specimen in 1908 by the Rev. C. Chichester in 

 the same spot. It is not in the last Census of the British Land and 

 Freshwater Mollusca by L. E. Adams, 1902, nor in the List of Non- 

 Marine Mollusca in the Victoria History of Devon, 1906, nor in 

 Taylor's Monograph. 



Limax arborum Bouch.-Chant. — Twitchen, wood. Numerous 

 on trees, more especially on the deciduous ones ; they occur in 

 clusters on the bark under moss, in which they make a hole and 

 which they loosen all round. Sometimes also in the armpits of 

 branches of firs covered by bundles of needles. One example 

 was observed on the wall of the house. Identified by Mr. Taylor. 

 None were met with in September, 1907, it being apparently too dry. 

 Very abundant in 1908, in similar positions, and in addition two 

 specimens were taken at Lee under stones. 



Agriolimax agrestis Linn^. — Twitchen, Borough Wood, Lee, 

 etc. Comm.on everywhere. 



[Milax gagates Drap. — Saunton. Typical form taken under 

 stones at the roots of herbage on the cliffs. Identified by Mr. Taylor. 

 Not recorded from North Devon in the last Census, nor in the 

 Victoria History^ but given by Mr. Taylor from North Devon, 

 p. T47 and p. 281]. 



var. plumbea Moquin-Tandon. — Borough Field. In 1908 

 three specimens were taken under stones, one in company with Arion 

 ater, the others with Agriolimax agrestis. Twitchen garden, another 

 example under a stone. Identification confirmed by Mr. Roebuck. 



Milax SOwerbii F6ussac. — Twitchen, Lee, [Also Braunton 

 Burrows, by Dr. G. B. Longstaff One of the specimens from the 

 latter place had a remarkably bright amber-coloured keel, and the 

 shell tinged with the same colour].
