eye, the cornea of which is chiefly situated on the ventral side of the stalk. The lateral 

 margins of the carapace are much convex, converging backward in their distal half, obtuse, 

 not keeled, and not dentate or notched, but puckled and pitted in an irregular way, the side 

 walls of the cephalothorax are for the most part covered with a thick toment of longer and 

 shorter, bearded hairs, growing gradually thicker in their terminal half; it are hairs of this 

 kind which are largely distributed on the maxillipeds (so as to render obscure their exact 

 shape) and along the chelipeds and walking legs. The hind margin of the carapace is convex, 

 but somewhat concave in the middle, accompanied by a very faintly-impressed line near the margin. 



Antennules very minute, neatly folded up beneath the front, perfectly transverse (in 

 Selwynia they are, according to Borradaile, folded somewhat obliquely). Antennae longer than 

 antennules, slender, hairless, about twice the length of the orbit. Epistome strongly folded 

 transversely, its hind margin thickened, not laminar and freely prominent, sulcate in the middle. 

 Anterolateral angles of buccal cavity much rounded, lateral margins subparallel, thickened, 

 adjacent parts of pterygostomian regions granulate beneath the toment. 



External maxillipeds scarcely gaping, ischium longer, ana also somewhat broader, than 

 merus (fig. 2a)-^ when the hairs covering the outer surface are removed, the merus turns out 

 to be subquadrate and widely different from that of Sehvynia laevis, as depicted by Borradaile : 

 its length is about equal to, and not greatly less than its breadth, the antero-external angle 

 is sharpened, not greatly rounded off, somewhat prominent, near the internal margin some 

 long, slender, feathered hairs are inserted ; the palp is very long (as in Sehvynia laevis), 

 but the carpus, instead of being inserted nearly in the middle of the anterior margin of the 

 merus, is implanted at the antero-internal angle of the latter. 



In my only specimen (a Q) the chelipeds are perfectly equal, rather bulky. Meropodite 

 very short, not projecting beyond the carapace, inner and outer margin thickly fringed, 

 outer surface granulate, upper margin unarmed. Wrist globular, with some scattered granules 

 near inner margin, inner angle very slightly prominent, but concealed beneath hairs. Chela 

 rather long, inflated, rounded at the margin; palm twice as long as the fingers, 

 smooth for the greater part, but the upper and basal portion of the inner surface thickly 

 tomentose, like the under portion of the outer surface, but beneath the soft fur numerous 

 granules are observed in the latter case; fingers short, straight, but strongly hooked towards 

 the tip, fixed finger more strongly crenulate at inner margin than opposite one, both fingers 

 tomentose, especially along the back of the movable finger (where also sharp granules are found 

 near the base) and in the gap of the fingers (fig. id). In Sehvynia (laevis) the chelae appear 

 to be hairless and the fingers are nearly as long as the palm. 



Walking legs slender, but short; first to third pair equal in length, little exceeding 

 length of carapace, last pair inconsiderably shorter. All the joints are thickly fringed 

 with hairs of the usual kind of this species. Meropodites slender, quite unarmed (in Selwynia 

 laevis a small tooth is found in the distal part of the posterior margin); carpo-, and especially 

 propodite, flattened, broadened; dactyli thick, conical, (with the tip slightly curved, horny and 

 hairless), equal in length to the preceding joints, whereas they are short, claw-hke 

 in Sehvynia (laevis)^ dactyli of last pair somewhat flattened and quite straight.
