few species, the type being Italian. The colour was not recorded 

 in the descriptions published by Thorell or Koch, as those authors 

 had spirit-specimens only. 



OllIBATIDiE. 



Oeibata setosa {K. L. Koch). 

 Several specimens. 



Oribata Pisheri, n. sp. 



Length about -48 mm. Breadth about "28 mm. 



This species is more closely allied to O. antarctica from South 

 Georgia (Beih. z. Jahrb. Hamburg. Ansr. v. p. 12, 1895) than 

 to any other, but is distinguished from it by the smaller size, the 

 lamellar hairs, interlamellar hairs, and rostral hairs not being 

 serrated, the form of the pseudo-stigmatic organs, and the wider 

 translamella. 



Pale olive-brown, slightly translucent. Lnmellae about half 

 the length of cephalothorax ; they are blades almost on edge and 

 narrow posteriorly, becoming gradually^ wider and more horizontal 

 as they approach their anterior ends. Cusps of the lamellae 

 very long, wide, almost horizontal, slightly truncated anteriorly ; 

 lamellar hairs springing from the middle of the truncated edge. 

 Translamella a narrow but very distinct blade on edge. Pseudo- 

 stigmatic organs very short, sessile, slightly curved, gradually' 

 thicTeened from the proximal to the distal end, which is truncated 

 but slightly rounded. Lamellar hairs, interlamellar hairs, and 

 rostral hairs long, thick, almost rod-like, not serrated. First 

 tectopedia without any free anterior projecting points. Abdomen 

 smooth ; progaster undulated, i. e. very convex in the centre, 

 coi'cave at the sides. Pteromorphae short, i. e. running only 

 about one-third of the length of the abdomen. A sparse line of 

 extremely fine hairs round the notogaster. Legs rather short, 

 fourth pair scarcely passing the posterior end of the abdomen ; 

 the coxse and femora of the third and fourth legs have distinct 

 blades. Claws tridactyle, but the lateral claws so thin as not to 

 be seen without a highish power. 



Several specimens from the talus. 



TlROGLTPHTD^. 



Gltciphagus domesticus {de Geer). 

 Two or three specimens from the talus.
