west coast to Westport and Grey mouth. Another fact pointing in 

 the same direction is found in the distribution of Armadillo speciosus^ 

 a terrestrial isopod. This is known from the North Island (Bay of 

 Islands, Dana, and Wellington, Sutton), and I have specimens from 

 Nelson; but I have never heard of it occurriug in the southern part 

 of the South Island." On either side of Cook Strait (Wellington, 

 Pelorus Kiver) specimens were found which show a marked approach in 

 the form of the rostrum, anteunal scale, etc., to P. Zealand tens. 



Faranephrops tenuicornLs Dana, from fresh-water streams about the 

 Bay of Islands, northern New Zealand, is described as having a short 

 point or tooth on the inner border of the anteunal scale, near the apex, 

 and the lower margin of the hand spinuli-scabrous, but not seriately 

 spinous. It is probably the same species as P. planifrons.

Types in British Museum (Miers). 



In P. zealandicus the chela is much shorter and broader than in 

 P. planifrons, and it is furnished with conspicuous dense tufts of silky 

 hair, disposed in longitudinal rows. The upper margin of the hand is 

 armed with a series of ijromiuent spines, continued as a double row on 

 the margin of the dactylus. The lower margin of the hand is furnished 

 with a double row of shorter spinous teeth. The outer face of the hand 

 is provided with a few tubercles, which seldom develop any spinous 

 points; the inner face bears two longitudinal rows of short teeth. 

 The rostrum is armed on e ich side with small, blunt teeth, usually five 

 in number, but in some individuals three, four, or six; the inferior 

 edge is either unarmed or else provided with oue or two acute teeth ; a 

 median carina runs over the gastric area, ceasing abreast of the ante-
