with serrated edges ; the feet are long and slender, the second is the 

 longest, a little more than ten times as long as the body, then come 

 the 4th, 3rd, and 1st, the last two being subequal, and a little more 

 than half the length of the first. The single claws are distinct only 

 on the two last pairs of feet. The abdomen is about one-third longer 

 than the thorax, with subparallel sides, and very obtusely pointed 

 posteriorly ; the surface is slightly convex, coriaceous, with the seg- 

 ments, — except the last three which are situated low down, — very 

 indistinctly marked ; a little before the centre it has a solid almost 

 perpendicular spine. On the lower side there are only five segments 

 very distinctly marked ; below the base of the sternum there is on 

 each side a small trachean opening. 

 Length of the thorax 2-2| m.m. ; its width 4.5 — 5 m.m.,

Loc. Neighbourhood of Calcutta ; I obtained a few specimens in 

 an old native hut, and some others among old branches of wood. The 

 animals are very quick in their movements. 



Gagrella signata, Stol. PI. XX, Fig. 10. 



The entire body is finely granular, a yellow line begins at the front 

 end of the thorax, divides just before the ocular tubercle, each branch 

 becoming widened and extending along the lateral margins of the 

 abdomen posteriorly ; the middle part of the abdomen is purely black, 

 the rest of the thorax and the feet brown with the joints darker, the 

 palpi and falces on the lower surface rather pale, the sternum and 

 abdomen partially ashy. 



This species which in general form resembles the former, differs 

 considerably in colouring. The body is rather short, or broadly oval ; 

 the cephalothorax has no spines in front, it has, however, a double 

 ridge posteriorly, but the margin is moderately concave. The abdomen 

 has one high and nearly perpendicular spine placed before the centre. The 

 under surface is also quite similar to that of the last species, the coxa? 

 being flattened and serrated on the edges &c, (see fig. 10 a). The most
