304 JOHN HEWITT. 



Labium. — With about twenty-four cusps on its anterior 

 half. 



Sternum. — Posterior sigilla elongated, about one and a 

 half diameters apart and about half a diameter distant from 

 the sternal margin. At the margin of the sternum opposite 

 the base of the second leg there is a deep circular depression 

 in which is situated the second sigillum ; a similar depression 

 also occurs in the female, but is not so noticeable, as the setse 

 which fringe its margin are not so strong as in the male. 

 Sternal margin fringed with strong bristles, especially pos- 

 teriorly. 



Posterior spinners. — Apical segment about three- 

 quarters the length of the penultimate segment. 



Measurements. — Total length 15"2 mm., length of cara- 

 pace 6"5 mm., breadth of same 4*8 mm., length of first 

 metatarsus 4 mm., of fourth metatarsus 5'8 mm. 



Bessia fossoria Foe. 



Bessia fossoria Poc, Ann. Mag. Nat. Hist., vol. vii, 6, p. 820, 



1900. 



I have examined the type, which is very immature, and 

 have now no doubt but that the much larger specimen from 

 Redhouse, referred to in a previous paper,^ belongs to this 

 species. The dentition of the paired tarsal claws was incor- 

 rectly described by Pocock, for the inner distal row is repi-e- 

 sented by two or three minute teeth on each claw. Moreover 

 the tarsus of the first leg and the distal half of the metatarsus 

 is rather strongly scopulate, the tarsus of the second leg is 

 scopulate at the sides, but the third and fourth tarsi ai'e not 

 scopulate. The teeth on the chelicerfe constitute a single 

 row, but the line is irregular, not straight. 



The genus is evidently very closely related to Spiroc- 

 tenus Sim.
