108 A new Genus of Arachnida, by Rev. O. P. Cambridge. 



nature, is thickly covered with minute round punctures, connected 

 in somewhat regular series, with slight groovings or wrinkles of 

 the skin ; and from each puncture there issues a short, strongish, 

 curved, pale amber-coloured diaphanous bristle. Ten small dark 

 red-brown points, or spots, in so many very slight depressions of 

 the surface, and forming two longitudinal lines, occupy the 

 median line of the upper surface ; from behind each of the last 

 two of these points runs a short oblique line or very slight in- 

 dentation. The underside has two small dusky red-brown spots, 

 one a little way behind each of the basal joints of the second 

 pair of legs. The genital aperture has a somewhat corneous 

 appearance ; it is of an oval form, convexly prominent, and 

 divided longitudinally by a gaping incision ; not far behind it is 

 the anal orifice, which is of the same form and character exter- 

 nally as the genital aperture, though not a fourth of its size. 



The eyes (seated as above described) are very distinctly visible ; 

 those of the foremost pair (forming the apex of the triangle in 

 which the three pairs are placed) are of a triangular shape, 

 closely contiguous to each other, and smallest of the six ; those 

 of each lateral pair are also contiguous, on a distinct tubercle, 

 the posterior eye of each being the largest of the six ; they are 

 of a pale dull amber-colour, and margined with red-brown. 



The legs are furnished with short hairs ; the basal joints are 

 the strongest ; the next are very short, and turned on the outer 

 side ; the tarsi, metatarsi, and femora of each pair are of very 

 nearly equal length ; the tarsi of the first pair are rather dilated 

 towards their fore extremities, and are (like those of the other 

 three pairs) cleft at the fore extremities on the upperside, two 

 apparently simple terminal curved claws springing from the 

 cleft. 



The palpi are very minute, and, with the other parts of the 

 mouth, placed at the bottom of a deep circular pit or cavity at 

 the extreme fore end of the body ; being thus minute, and sunken 

 below the surface, as well as covered with the hairs fringing the 

 cavity, their form and structure could not be ascertained with the 

 magnifying powers at my disposal. 



Two examples (both females) of this remarkable Acarid were 

 received, among numerous spiders, from Mr James Hardy, of 

 Oldcambus, Berwickshire, by whom they were found (probably 

 among moss) on Cheviot Hill. It is unlike anything I have ever
