Material. — I have examined one speeimen ( ? ) of the 

 variety from Kauai, one of the most western islands of the 

 Sanrlwich Archipelago. 



Remarks. — As I have only seen three specimens of this 

 species, 1 have not thought it advisable to establish tlie variety 

 as a new species ; but, on the other hand, as the differences 

 seem to be well marked and as the specimen is from another 

 locality, I think that the description of the differences 

 will be of value to future workers. It would be interesting 

 to investigate the relation between the geographical distri- 

 bution and the variations. 



Chelifer pacificus, sp. n. (PI. VII. fig. 2 a.) 



Cephalothorax. — Xo eyes or ocular spots a e present. The 

 cephaluthorax is a little longer than broad ; it is more dis- 

 tinctly pi'oduced in front and with a better-marked median 

 incision than Ch. hawaiiensis ; the almost straight transverse 

 grooves are indistinct ; the skin is distinctly but minutely 

 granular and the distinctly clavate hairs are almost as long 

 as broad. 



Abdomen. — The abdomen is distinctly longer than broad ; 

 the tergites have their sclerites jjoorly developed, and the 

 first three are only in a slight degree shorter than the other; 

 both the anterior and the p( sterior margins are almost 

 straight. The whole surface of the tergites, including the 

 indistinct longitudinal line in the middle, is shagreened. 

 Eight transverse rows of clavate hairs are present as well as 

 some few hairs (lateral) in front of the row on the median 

 segments. Genital area scarcely difl'erent from that found 

 in ( //. haivaiiensis, Sim. 



Ante/iuce. — The Jiagellum consists of four hairs. The 

 lamina interior possesses three or four lobes, the teeth of 

 Avhich are comparatively short ; the terminal spine, which is
