divided. Each tarsus lias a not very dense scopula beneath it, 

 least dense on those of the third and fourth pairs. 



Falces strong, projecting, and armed with some strong, curved 

 claws at the fore extremity, just in front of the base of the fang. 



MaxilJcB cylindrical, divergent ; the inner corner of the anterior 

 extremity very slightly prominent. 



Labium short, slightly hollow-truncate at the apex, which is but 

 little less wide than the base. 



Sternum oval, rather broadest behind. 



Spinners two only ; moderate in length and strength, two-joiuted, 

 and upturned. 



DiPLOTHELE WALSHi, sp. u. (Plate XLIII. fig. 1.) 



Length of an immature female, rather over 4 lines. 



The colour of the cephalothorax andya^ces is pale yellow-brown, 

 the normal converging indentations marked by darker lines ; the 

 thoracic indentation is moderate in depth, curved, the convexity of 

 the curve directed backwards ; the surface is furnished with hairs and 

 slender bristles. The profile line of the caput is slightly curved 

 behind the ocular protuberance, but runs off pretty evenly and 

 gradually to the hinder margin. The posterior side of the ocular 

 protuberance is abrupt, the anterior rather less so. 



The fore lateral eyes are largest of the eight, next are the fore cen- 

 trals, and the hind centrals are the smallest ; these last are contiguous 

 to the hind laterals, and with them are of a shining white colour ; the 

 fore laterals are pearly, the fore centrals dark grey. The latter are 

 placed on a largish black patch, the rest are more or less widely edged 

 with a similar colour. The fore laterals are seated on the anterior 

 slope of the protuberance and look straight forward ; between them 

 are a few strong black recurved bristles. 



The legs (together with the palpi, which are leg-like and similarly 

 furnished) are of a yellow hue, as also are the maxillae, labium, and 

 steruum ; towards the hinder extremity of the upperside of the tarsus 

 of each of the first two pairs of legs and of the palf i is a group of 

 three or four black, clavate, or racquet-shaped hairs. 



The falces are furnished with numerous hairs and strong bristles, 

 besides the rdteau of curved spines at their fore extremity on the 

 upperside. The fang is strong, curved, and of moderate length. 



The abdomen is oval, of a dull clay-yellow colour, marked on the 

 upper part and sides with broken transverse black fasciae of varied 

 width and clearness of definition, those on the anterior half being the 

 strongest and best defined ; it is clothed above with hairs and a few 

 slender bristles, underneath with hairs only. 



The spinners are two only in number and two-jointed, unless the 

 small but distinct portion at the extremity, on which the spinnerets 

 (or spinning-tubes) are placed, be taken to form a third joint. 



An immature female of this very interesting and remarkable Spider 

 was sent to me from Orissa, Calcutta, by Dr. Walsh (of the Calcutta 

 General Hospital). The possession of only two spinners differentiates 

 it from all others of the Theraphosidce known to me, and by this, as 

 well as by other important characters, such as the possession of spines
