the remaining palp of the holotype, which could not be measured without removal, do 

 not differ perceptibly from those of a "Terra Nova " specimen of which the measure- 

 ments are given above. The very small number and the simple form of the special 

 spines on the ovigers are, as Hodgson has pointed out, unusual characters of this 

 species. In a male from the "Terra Nova" collection the numbers of spines on the 

 last four segments of the oviger are 2:1:1:1.
