18/6.] ARACHNIDA FROM KERGUELEN's LAND. 259 



all of them are remarkable ; all appear to be new to science ; and one, 

 indeed, at present seems to me incapable of inclusion in any hitherto 

 recognized order of Arachnids. The whole collection consisted but of 

 five species ; one of Araueidea and three of Acaridea, the fifth being 

 that upon which I propose to found a new genus, family, and order. 

 At first sight this delicate little Arachnid gave me the idea of a Che- 

 lifer deprived of its forcipated palpi; but a subsequent examination 

 with a stronger lens showed me that it possessed palpi of an entirely 

 different character from those of the pseudo-Scorpiones ; and a final 

 scrutiny under a still higher power led to the detection of the eyes : 

 in the number and position of these there is a remarkable similarity 

 to the Solpugidea, while there are not wanting some general indica- 

 tions of affinity to the Araneidea. Its small size and general ap- 

 pearance when alive would probably induce one to place it among the 

 Acaridea ; but the structure of the mouth-parts, the distinct cephalo- 

 thorax and abdomen, and especially the character of the eyes seemed 

 to preclude this allocation. It is possible, however, that when the 

 Acaridea have been more thoroughly worked out by some future 

 arachnologist, the present anomalous little creature may become the 

 type of a suborder, or perhaps only of a family of that order. 

 Meanwhile in forming a distinct order for its reception, I desire to 

 obtain the free criticism and opinion of arachnologists more conversant 

 than myself with some obscure groups of Acaridea, as to its true 

 systematic position. 



Order Acaridea. 



Fam. Acarides. 



Gen. nov. Torynophora. 



Body oval ; a slightly indented transverse line towards the fore part 

 on the upperside appears to mark the junction of the cephalothorax 

 and abdomen. 



Mouth-parts almost soldered together, leaving only the short palpi 

 and the extremities of the falces traceable. 



Legs 8, slender, in 4 pairs (1-2 and 3-4 on each side), 5-jointed, 

 and terminating with two somewhat S-curved claws springing from 

 a small supernumerary or heel-joint. 



Eyes four, in two pairs, one pair on either side of the caput. 



Falces armed on the underside with seriated opposed edges. 



Palpi short, strong, 4-jointed, with a single strong curved jaw-like 

 claw springing from its base on the upperside. 



Torynophora serrata, sp. n. (Plate XIX. fig. 1.) 



Length \ line. 



This minute Acarid is of an oval form, tolerably convex above, and 

 of a uniform pale luteous colour. From the fore part of the cephalo- 

 thorax four pointed processes project, each one terminating with a 

 very small joint, from which springs a curious clavate or spoon- 

 shaped bristle or tag ; a few with a somewhat similar tag are dispersed 

 thinly over the upper surface of the bodv, which is closely wrinkled,
