THE AFGHAN DELIMITATIO>: CO-MMISSION. 113 



tarsi of the first aucl second pairs furnislied beneath witli sev^eral strong spines ; tibia and 

 metatarsus of the fourth pair of legs about equal in length. 



Labium rounded, clothed in front with long hairs ; coxa? of all the legs beset witli 

 coarse hairs ; sternum longer than wide, wider in its posterior than in its anterior half. 



Measurements (in millimetres). — Length (from margin of clypeus to end of abdomen) 

 19^ ; of cephalothorax 8, width 6j ; length of sternum 4J, width 3f : length of legs 

 (with coxoe), first 22J, second 19^. 



One female specimen from Gulran. 



With respect to the equality in length between the tibia and metatarsus of the fourth 

 pair of legs, this species resembles N. badia and N. macrocejihala, described respectively 

 from Corsica and Palermo by Ausserer (Verb. k.k. zool.-bot. Ges. Wien, xxi. p. 166, &c., 

 1871). From 'N. badia it may be distinguished by the existence of the small teeth upon 

 the maxilla, and from J^. niacrocephala by the entire absence of spines upon the tarsi of 

 the first and second 2iairs of legs. 



[This Spider was found in numbers over the plains of Gulran (4th March, 1885). The 

 entrance to its abode, consisting of a well-defined inlet about three quarters of an inch in 

 width and without a cover, was easily seen ; this was the aperture into a passage that led 

 perpendicularly down into the soil to a depth of eighteen inches ; this passage was lined 

 wdth a very thin layer of a giey silk web, only of suificient consistency to ^irevent the soil, 

 which was a soft, sandy loam, from falling in and filling up tlie passage. The Spider was 

 caught at the bottom of the passage, which ended abruptly, by dropping in a piece of 

 stick the length of the tube, and then digging away the soil round it until the end of the 

 passage was reached. — J. E. T. A.] 



SCORPIONIDEA. 



5. BuTHUS PARTHORUM, sp. n. (Plate XIII. fig. 3.) 



Colotir. — Cephalothorax and abdomen fusco-testaccous ; legs testaceous, palpi and tail 

 a little darker than the legs. Eyes and hinder half of aculeus black ; cephalothoracic and 

 abdominal keels dark-coloured. 



Ccplialotlwrux. — Anterior border lightly concave, wider posteriorly than it is long; about 

 twice as wide behind as it is in front ; the arrangement of the keels almost resembling 

 that of B. peloponnensis, C. Koch [gibbosus, Brulle), the granules of the anterior keels 

 extending from the hinder portion of the ocular tubercle to the anterior margin of the 

 cephalothorax ; near the anterior border the granules decrease in size, and curving 

 inwards meet in the middle line with those of the opposite side. The eyes are a little 

 more -nddely separated than in B.x>eloponne)isls, and this circumstance, in connection with 

 the conflvience in front of the granules on each side, constitutes the most noticeable dift'er- 

 ence between these anterior keels and those of B. peloponnensis. The area surrounded by 

 these keels is almost smooth behind, but in front is beset with very fine granules. The 

 area between the anterior half of each anterior keel and the lateral eyes of the same side 

 is beset, but not closely, with granules; and behind and externally to this granular area
