Length of the male rather over 2£ lines. Female somewhat 

 larger. 



Closely allied, and very similar, hoth to Pirata piraticus, Clk. 

 (p. 353), and Pirata piscatorius, Ibid. (p. 351). It is, however, not 

 nearly so large as the latter, and differs in the form of the lateral 

 and central bands on tho cophalo-thorax. Tho central band is 

 irregular on tho odges, strongly constricted just at the hinder 

 part of the caput, and has its fore part almost entirely occupied 

 (excepting a marginal line) by tho dark, tapering, or spear- 

 headed marking. Tho marginal bands are also very irregular, 

 or jagged, on their upper edges, and are (apparently) less con- 

 spicuously clothed with white hairs than in Pirata piscatorius. 

 The samo differences distinguish it also from Pirata piraticus* 

 From both it also diffors in having the legs distinctly annulated 

 with light yellow-brown and deep brown. It is also a rnoro 

 hirsuto spidor than Pirata piraticus, and has a dark brown 

 sternum in tho female, partly divided in front by a longitudinal, 

 central, yellowish stripe. From Pirata hygrophilas (p. 352) it 

 may be distinguished by its smaller size, and more distinctly 

 annulated legs ; also by the pale marginal bands of the cephalo-
