Cratinella laticeps new sp. 



Length 1*5™™. Cephalothorax and abdomen dark reddish brown, 

 the cephalothorax a little lighter. Legs yellow. Hardened spot 

 covering the whole top of abdomen. Male palpi short like laetabilis 

 which this species resembles. The cephalothorax is wide in front 

 and concave between the eyes, the lateral pairs being widely sepa- 

 rated from the others and carried a little forward (PI. ii, fig. 2). 

 The head is high just behind the eyes (PI. ii, fig. 2a), and has a few 

 stiff hairs in a row in the middle. The back part of the cephalo- 

 thorax is slightly roughened. 



The male palpi resemble those of the other species with short 

 palpi. The patella and tibia are of equal length, the patella as 

 wide as long and the tibia widened with a process with a sharp 

 recurved point on the outer side. The tube of the palpal organ is 

 longer than in most species, the basal half having a projecting tooth 

 beyond the beginning of the terminal half, (PI. ii, figs. 2c, 2d). 



One male only from near Laggan.
