spicuous large prominence, white before, black behind, with others, 

 smaller, both along the margin and side, before and behind it, and 

 a row round the fore margin ; there are also many much smaller 

 tubercles over the surface, arranged somewhat symmetrically. The 

 general colour of the abdomen above and on the sides is yellow- 

 brown mixed with black-brown, black, and white ; and between 

 the anterior prominences of the central quadrangle is an elongate 

 longitudinal white marldng divided longitudinally by a dark-brown 

 line, and on each side of its hinder end is a shining dark-brown 

 tubercle. Spinners short, strong, very compact, and of a yellow- 

 brown hue. 



Hab. Ceylon. Eeceived from the late Mr. Gr. H. K. Thwaites. 



Talaus oblitus, sp. n. (Plate XXX. fig. 8.) 



Adult male, length slightly over I5 line (or nearly 3 mm.), 



Gejilialotliorax a little longer than broad ; somewhat subquadrate, 

 the anterior side a little rounded, the posterior rather impressed 

 and nearly as long as the anterior. Upper surface regularly convex, 

 the normal grooves, indentations, and lateral impressions at the 

 caput obsolete ; heigbt of clypeus less than half that of the facial 

 space, and its profile follows the general slope of the foi'e part of 

 the caput. The surface of the cepbalothorax is covered, especially 

 on the sides, with impressed spots or pock-marks, and with 

 scattered, strong, erect spiny bristles issuing from transparent 

 tubercles ; these bristles, however, terminate in a curved transverse 

 line at the upper part of the hinder slope. Its colour is a brightish 

 yellow-brown. 



Eyes in two very strongly curved lines, their convexity directed for- 

 wards (the posterior cur\ e stronger) and occupying very nearly the 

 whole width of the caput, or perhaps they may be more conveniently 

 described as in three groups — a central quadrangle of four minute 

 eyes broader than long, with its anterior side shorter ; at a distance 

 considerably greater than the space between the posterior eyes of 

 the quadrangle and on each side of it, are two much larger eyes 

 (the anterior the larger) in a slightly oblique longitudinal line, 

 seated on a strong common prominence, and separated from each 

 other by double the diameter of the posterior eye. The posterior 

 eyes of the quadrangle with the anterior eyes of the latei-al pairs 

 form a very slightly curved line, the convexity of the curve directed 

 backwards. 



Legs moderately long', slender, 2-1-4-3, 2 and 1 much longer 

 but not very different in length. They are furnished with long 

 slender prominent bristles, a tew of which are spiniforni, and irre- 

 gularly disposed. The femora ai-e somewhat granulose or furnished 

 with some minute tubercles ; they have neither scopula nor terminal 

 claw-tnft. The terminal claws are strong, those of the first and 

 second pairs closely set with long pectinations, while the pecti- 

 nations of those of the third and fourth pairs are short and fewer. 

 The colour of the legs is similar to that of the cepbalothorax. 

 Falces rather long, strong, conical, the anterior part somewhat
