DISCOVERY REPORTS 



First pair of legs longest, then fourth, second and third pairs. First and fourth pairs 

 slender, second and third pairs stout, fourth pair the most slender and second pair the 

 stoutest of the legs. Claws and general arrangement of hairs much the same as in other 

 species of the genus. Arrangement of hairs and spines in the sensory area of leg I 

 specifically distinct (Fig. 8). 



Stigmata lying between legs III and IV scarcely visible from dorsal view. Peritre- 

 matal plate very slightly chitinized and difficult to distinguish, elongate and slender, 

 resembling that of H. zalophi rather than H. rosmari (Fig. 9). The position of the stigma

of leg I of female. Fig. 9. Peritrematal plate, stigma and tracheae of female. 



in relation to the peritrematal plate is seen in Fig. ()b ; Fig. 9^ was drawn from a pre- 

 paration in which, as frequently happens, the stigma has been twisted out of position. 

 Tracheae dividing into seven branches, three curving round anteriorly and four 

 posteriorly. Lying a little distance in from the peritrematal plate is a duct, the proximal 

 portion closely coiled, the distal portion free. In some preparations the free portion 

 of the duct runs straight back to the region of the fourth coxae, in others the duct 

 stretches across towards the genital Hp, and in the preparation figured the duct curves 

 back over two of the tracheal trunks. What the function of this duct is I do not know. 

 Male (Fig. 10). Smaller than the female, podosoma more rounded, opisthosoma 

 more slender. Dorsal, lateral and anal plates as in female. Tritosternum absent. Sternal 

 plate extending from the anterior border of coxae II to middle of coxae IV. General 

 form somewhat elongate heart-shaped, anterior margin bilobate. Genital aperture in 

 middle of anterior margin. Penis highly chitinized. Chelicera (Fig. 12) a strong, stout 

 appendage ; first article broader than long, second article one and a quarter times longer
