630 Mr. S. Hirst on yiew Opiliones from 



Material. — A single male example, collected by Mr. S. 

 Akiyama at Idzu^ Japan (June 1910). 



Remarks. — Apparently rather closely allied to the East- 

 African species described (under the generic name Palpipes) 

 by Dr. W. Sorensen, but it can be readily distinguished 

 from them by the number of the tarsal segments of the 

 anterior legs and by the armature of the scutum &c. 



In the three species that I have been able to examine (the 

 two new species described in this paper and S. gardineri, 

 Hirst) the segments of the posterior tarsi are five in number; 

 Dr. Sorensen states in his description of the three East- 

 African species that the tarsi of the posterior legs are divided 

 into four segments, but perhaps he has overlooked one of the 

 segments. 



Sifalces indicus, sp. n. 



Body about as long as the tibia of the fourth leg and very 

 much shorter than the tibia of the second. 



Scutum bearing a number of processes and enlarged 

 granules, which are arranged in transverse rows, a row being 

 situated a little in front of the posterior margin of the 

 cephalothoracic area and also one on each of the abdominal 

 segments (the limits of which are difficult to make out). 

 The central processes, which are paired, are mostly of 

 large size; those of the central pair of the fourth abdominal 

 segment are the longest of all ; next in size come those 

 of the middle pair of the cephalothoracic row, but they 

 are much shorter than those of the fourth abdominal ; shorter 

 still are those of the first, second, and third abdominal seg- 

 ments ; in the third segment the process which is situated on 

 the outer side of those of the middle pair is equal to tiiem in 

 size or even longer. A number of tooth-like projections are 

 placed along the anterior margin of the scutum (on each side 

 of the ocular tubercle) and one is present on the arch-like 

 structure which joins the ocular tubercle. The coarse 

 granules which bear hairs are not very numerous in this 

 species, a large proportion of them being situated in the 

 transverse rows ; in the middle of the scutum between the 

 larger processes they are entirely absent, but a few scattered 

 microscopic granules are present there and on other parts of 

 the scutum. Ocular tubercle high, conical, and very much 

 more erect than that of S. ahiyamce, sp. n. ; the three prin- 

 cipal processes are very well-developed, the two anterior ones 

 being very long, especially the anteriormost ; besides these 

 three processes a number of granules are present, not only on
