NOTHRUS GLABER. 525 



may be known by its much larger size, smooth (not 

 reticulated) cuticle, more pointed rostrum, &c. 



Colour yellow-brown, of medium depth of tint. 



Texture smooth, but not shining, ivithout any reticu- 

 lation. 



Cephalothorax rather long, much narrower than tlie 

 abdomen. Rostrum more elongated than that of N. 

 tardus, rather narrow, but the actual tip is rounded ; 

 rostral hairs rather long and set far back. The chelae 

 of the mandibles are fine, long, and straightish, meeting 

 only near the ends, and but slightly dentate. No 

 exterior pseudo-stigmata of the ordinary tubular pro- 

 jecting type are visible ; there is, however, a long seti- 

 form hair on each side, as in iV^. tardus (see that species). 

 Apodemata joined to the sternum, which, however, 

 is broken between the second and third pairs of legs. 



Legs short, not very thick ; the first pair pass the 

 tip of the rostrum by about half the length of the 

 tarsi ; the fourth pair reach beyond the middle of the 

 anal plates ; the third and fourth pairs are set a good 

 deal under the abdomen, as in N. tardus. Tibiae not 

 longer than the genuals ; tarsi the longest joints. 

 They bear two or three almost spike-like hairs in the 

 upper median line and a few true spikes in the median 

 line below (but they do not bear the tooth-like pro- 

 cesses of iV. monodadylus). The other joints have a 

 few setiform hairs. Claws tridadyle, central claw 

 much the shortest. 



Abdomen flat, shield-shaped. Progaster almost 

 straight uitJumt projecting corners ; hind margin almost 

 pointed. There are two longitudinal rows of about 

 three setiform hairs each on the notogaster. Genital 

 and anal plates close together, the former considerably 

 broader than the latter. At the anterior inner corners 

 of the genital plates, and within the abdomen, are two 

 paired processes for the attachment of muscles, which 

 processes are remarkably large and of dark chitiu, so 

 that when the specimens have been rendered trans- 

 lucent and mounted in balsam, these processes become
