the coxfe are short and spincd^ those of the fourth pair are 

 loiif^cr and more slender. 



Lc(/s. — The ordinary hairs of the legs are rather short, 

 stift', and clavate ; they are cnharfjed terminally and there 

 provided with short branches in all directions. The ventral 

 hairs of the tarsus are much longer and more slender than 

 the dorsal ones; they are not simple, but spined distally. 

 The claws seem never to bear teeth, but have an inner and 

 outer bifurcated hair near the base as in Ch. cancroides, L. 

 (PI. YIII. fig. 2//) ; this structure I have observed only in 

 tarsi of a cast skin. The first legs have a very well-developed 

 trochantin ; the tibia is distinctly enlarged distally and as 

 long as the tarsus. The fourth legs have the tarsus enlarged 

 distally and shorter than the tibia. 



Colour. — The palps, maxillae, liead, and coxre are reddish 

 brown, with a more or less pronounced purple shade. The 

 raised band of the tergites is bright brown, while the de- 

 pressed spots are more yellowish brown ; sternites yellowish 

 brown wath a blackish shade. The whole dorsal surface is, 

 when lighted, more or less metallic. 



Measurements. — Cephalothorax 1-4 (0-42-1 -68) ; abdomen 

 2-1 (2-492) mm. 



Palps: trochanter 0-644 (0-448); femur 1-2G0 (0-540); 

 tibia 1-148 (0-540); hand 0-1)82 (0-576), height 0-550; 

 fingers 0-812 mm. 



Leg i. : femur 0*840 (0-308) ; trochantin 0-392 ; tibia 

 0-560 (0-210) ; tarsus 0-560 mm. 



Leg iv. : femur 1-094 (0-415); trochantin 0'336; tibia 

 0-728 (0-250) ; tarsus 0-600. 



$. Cephalothorax. — The anterior groove is distinctly 

 curved backwards. The granulations are less marked than in 

 the female. 



Abdomen. — The lateral projections of the tergites are much 

 better marked than in the female. That of the second 

 thoracic tergite is comparatively insignificant ; those of the 

 abdominal tergites attain their highest development in the 

 sixth and seventh segments, and are there long, free, and 

 similar to a keel, directed obliquely upwards, outwards, and 

 backwards. The raised transverse bands, and especially the 

 hindmost row of depressed spots, seem less marked than in 

 the females. 



The fourth sternite differs from the corresponding one in 

 the female by being half as long and almost as broad as the 

 fifth. 



Genital area (fig. 2 h). — The genital area is most similar to 

 that found in Chelifer cancroides, L., and the species which are
