Material. — The Danish Galathea Expedition has taken a single, very muti- 

 lated female at Nankovry, one of the Nicobars. 



Remarks. — It is only with some hesitation, that I have established this 

 new species in stead of referring it to Pseiidochiiidiiim clainyerum Thor., but it 

 was found most obvious to do so on account of its elongate abdomen, more 

 rounded posterior process of the trochanter and the hand, which is more abruptly 

 convex just beyond the stalk.

Céphalothorax with two broad prominent transverse, almost straight grooves, 

 distinctlij granular with broad clavate hairs. The short abdomen is distinctly broader 

 than long with the two halves into which the median tergal sclcrites are divided by a 

 broad longitudinal line, establishing an obtuse angle with each other; tergites are 

 distinctly granular, only possessing a single row of clavate hairs. The distinctly gra- 

 nular palps are a little longer than the body; the trochantin is slightly longer than 

 broad and broader than the femur with its posterior surface produced into a long 

 triangular and pointed process; the femur is 2 6 longer than broad, and narrower than 

 the tibia, which has the lateral outlines distinctly coiu>ex. The hand is 12 broader 

 than the tibia, li) longer than broad and V5 longer than finger. The tarsus of the 

 first pair of legs is 14 longer than the tibia. 



Body. — The céphalothorax is not broader than long, and the transverse 

 grooves are straight. The abdomen is very broad and flat, as it is distinctly 

 broader than long. 



Palps (PI. IV, fig. 13 a). — The palps are a little longer than the body; the 

 trochanter is only 12 longer than broad and has the posterior margin prolonged 

 into a very long, somewhat triangular and rather pointed process. The lateral 

 outlines of the tibia are more distinctly convex. The hand, which is 1-9 longer 

 than abrod and 15 longer than the finger, is less abruptly convex beyond stalk 

 than in P. Thorellii n. sp. The femur of the fourth pair of legs is 31 times longer 

 than deep and a trifle longer than the tarsus; the tarsus of the first pair is 14 

 longer than the tibia.
