Show 260 REV. O. P. CAMBRIDGE ON NEW [Feb. 15, the wrinkles taking different but regular directions on the different parts of the body. The eyes are very minute, in two pairs, one on either side of the caput ; those of each pair are near together but not contiguous. The legs are 5-jointed, slender, and not very long ; they are armed with fine spines, bristles, and hairs, and terminate with two tarsal S-shaped claws, springing from a small terminal joint, and furnished beneath with some slender prominent clavate hairs. The legs are in pairs, the first and second, and third and fourth legs on each side having their basal joints respectively contiguous to each other, as in the genus Trombidium, and articulated to the fore half of the lower surface of the body. The palpi are short, strong, 4-jointed ; and to the upperside of the base of the digital joint is articulated a strong curved claw. The maxilla, labium, and falces coalesce and form a kind of suctorial apparatus, towards the fore part of which on the underside are two opposed curved saw-edged processes. Several examples of this curious Acarid, found under stones, were contained in the Rev. A. E. Eaton's Kerguelen's-Land collection. Being so very minute and delicate, they had suffered considerably by being preserved in strong spirit. Fam. BDELLIDES. Gen. S C I R U S , C. Koch? S C I R U S P A L L I D U S , sp. n. (Plate X I X . fig. 2.) Length | a line. As far as I could ascertain from the single example contained in the Kerguelen-Island collection, this small Acarid is an undescribed species of the genus Scirus. Its colour is a dull yellowish white; and there are a few obscure blackish markings in two parallel longitudinal lines along the upperside of the abdomen. The body and legs are furnished with a few longish pale semidiaphanous hairs. The eyes are in two pairs, those of each pair contiguous, and in the position indicated by the two small oval markings in figure 2 b. The only example received was injured by the action of the spirit in which it had been preserved, so that the exact details of its structure could not be satisfactorily observed ; in the general appearance, however, of the beak-like mouth-parts there seemed to be but little difference from the genus Bdella and others nearly allied.
