8. Hinzuanius parvulus, n. sp. (Fig. 10). 



Colour. Body dark brown ; distal ends of the tibiae of the second and fourth legs 

 white ; the distal tarsal segment of the third and the distal end of the metatarsus and 

 the tarsal segments of the fourth are also pale-coloured ; the 

 remaining segments of the legs being dark brown in colour. 



$. Scutum. Dorsal surface of scutum and free segments 



roughened with minute granules and entirely unarmed. Eyes 



situated on the outer sides of very slight elevations, and very 



widely separated from one another ; they are separated from the 



lateral margins of the scutum by an interval which is rather less Fig. 10. Hinzuanius par- 



than twice the diameter of an eye. Cephalothoracic area marked !"^f' n ' sp ' Pal P from

off from the rest of the scutum by a deep groove ; a fine trans- 

 verse groove is also present a little in front of the posterior margin of the scutum, and 

 it is connected with the anterior transverse groove by a pair of fine lateral (longitudinal) 

 grooves (one on each side of the scutum), which run parallel to the outer margins, and are 

 continued a little distance forwards (after joining the anterior transverse groove), coming 

 to an end below the eyes. 



Palp very long and slender. Femur of great length and armed below with a few 

 minute spines. Patella longer than tibia, and with only a very short narrowed portion 

 at the base, the rest of the segment gradually increasing in stoutness ; it is armed with a 

 single apical spine on the inner side. Tibia with two inner and three outer spines. Tarsus 

 equalling the claw in length and armed with two spines on each side (Fig. 10). 



Legs. Proximal tarsal segment of the two posterior pairs of legs longer than the four 

 distal segments together. Number of tarsal segments 3, 5, 5, 5. 



Measurements in mm. Length of body 2 '25, of palp (including trochanter), 3 '9. 



$. Resembling the female very closely in colour and in almost all the structural 

 details also. The structure of the tarsi of the posterior legs is strikingly different, how- 

 ever ; the number of tarsal segments of these legs is the same as in the female, but the 

 second segment of the tarsus of the third leg is much swollen and about twice as long 

 as the proximal segment ; whilst the corresponding segment of the fourth leg is a little 

 swollen, but is shorter than the proximal. The mandibles are not enlarged, but the 

 genital operculum is distinctly narrower than in the female. 



Measurements in mm. Length of body 2'25. 



Material. Two females and a male from Praslin. 



Remarks. The genus Hinzuanius is practically confined to the countries bordering 

 on the Indian Ocean. In the Oriental region, species have been recorded from Sumatra, 

 the Malay Peninsula, Burma and India. In the African continent and neighbouring 

 islands, species are known from Abyssinia, the islands of Socotra and Abd-el-Kuri, Natal, 

 Cape Colony, and from Madagascar. 



The new species from the Seychelles does not appear to be very closely allied to any 

 of the previously described species of the genus. The chief characters by which it may be
