XXXVIII. — T/ie Land Isopodn of Lxtndjj Island. 

 By BliUCli F. CUMMINGS. 



In June tlii.s year I spent a few days on Lundy Lsland and 

 dt'votcd a snuill portion of my time there to cctllectinp^ the 

 hind Isopoda, no list of which has, so far as I am aware, 

 been hithi-rto drawn up. ]\Iy short search for the woodHce 

 ct-nvinced me tliat more prolonged and more careful study 

 would reveal a far richer harvest of species than that indicated 

 in the list below. 



Ligia cceanica, L. — Very common on the beach near tlie 

 landing-j)lace. 



Tn'choniscus piisillus, Brandt, — Common everywhere. 



Trt'choni'scus 7'oseiis, Koch. — I captured a small specimen 

 in the garden of the Rev. Hudson G. Heaven, who is the 

 owner of the island, and to whom I am indebted for permission 

 to enter his private grounds. 



Tri'chontscHS pyifmccus^ G. O. Sars. — Two specimens in 

 ]^Ir. Heaven's garden. 



Oniscus aselhis, L. — Very common in its typical form. 

 There is also a very handsome island variety of a butterscotch- 

 yellow colour. 



Philoscia muscorum, Scop. — Very frequent both in the 

 cultivated and uncultivated ])ortions. Tlie dark brown-black 

 and the light lemon-coloured varieties both equally common. 

 I also took a pink sjiecitnen, which not uncommonly is found 

 on the mainland in North Devon. 



Philoscia couchiiy Kin. — Common near the landing-place 

 with Ligia. Those >Ahich I observed were of the typical 

 lead-grey tint. 



Flatyarthrus hoffmannseggii^ Brandt. — Abundant in the 

 nests of the yellow ant [Forniica Jlava) . 



Porcellio scaler^ Latr. — Abundant everywhere in its 

 various colour-varieties. 



Cylisticus convexus^ De Geer. — I obtained a single specimen 

 of this animal. 1 looked carefully for more, but was unsuc- 

 cessful. 



Arniadillidium vulgare, Latr. — Very common everywhere. 

 I obtained a number of small specimens, which I thought 

 were the young of Arm. 7iabatu7n, but Dr. Norman, to wiiom 

 I submitted them, told me that it was a form which he had 

 from several places close to the sea, but which he was unable 

 to distinguish from Arm. vuJgare. 



Of the above eleven species, Cylisticus convexus and
