 A. vulpes Bertk.)." 



Since Thalassius, Sim., both according to Simon's diagnosis and 

 the type of T. unicohr Sim., now before me, possesses 3 teeth only 

 on the lower margia of the fang-groove, I am unable to agree 

 that Dolomecles spathularis Van Hasselt belongs to this genus, as 

 Simon states (see above). 



That it is one of the Cteniform Lycosidee appears highly probable 

 from the fact that the fourth pair of legs are the longest, though 

 Van Hasselt makes no mention of the number of tarsal claws, which 

 alone is a sure criterion.^ 



Females. 



a. Carapace and abdomen unicolorous, without lateral 



pale bands. Tibia i. very slightly longer than 



carapace T. imieolor E. Sim. 



b. Carapace and abdomen with pale lateral bands. 



Tibia i. as long as or shorter than carapace, 

 i. Tibia i. as long as carapace.

Colour. Entirely unicolorous yellow-ochreous. Carapace and legs 

 clothed with close, fine, hoary-white pubescence. Abdomen dull 

 ferruginous yellow, unicolorous. 



Structure. See generic diagnosis, p. 28. Vulva, Plate IV. fig. 2. 



This form can be recognized by the absence of white bands on 

 the carapace and abdomen.

} Since writing the above a specimen obviously identical with Van Hasselt's 

 D. spathularis has come before me from Deli, Sumatra. It is a true Dolomedes 

 and not a JTialassins or Dolopceus, having four teeth on the fang-groove and 

 three tarsal claws.
