The following is the description of tlie largest specimen, a 

 female, found at ElpMnstone Island, 



In its outer appearance P. Andersoni somewhat resembles the 

 common Indian P. vespertilio, Eabr., but it is of smaller size 

 and much less hairy. The cephalothorax is about once and a 

 half as broad as long, the proportion of the breadth to the 

 length being as 25 to 18. The upper surface is tolerably convex 

 longitudinally, and much less convex transversely; it is much 

 declivous anteriorly towards the front, and also somewhat towards 

 the lateral margiDs. The regions are faintly and only partly 

 indicated, the inter-regional grooves, so far as they are present, 

 being rather shallow. The two small, rounded, epigastric lobes, 

 which are separated as usual from one another by the median 

 frontal furrow, are a little prominent ; the frontal furrow is bi- 

 furcated immediately behind them, and the two parallel grooves 

 into which it is divided, which border the mesogastric area, 

 diverge backwards and terminate in the gastrobranchial grooves. 

 The latter are very shallow though yet distinct ; their ex- 

 ternal transverse portions, separating the hepatic and epibran- 

 chial regions from one another, are a little deeper than the 

 median portion, and the upper orbital margins are surrounded 

 by a shallow groove which separates these margins from the 

 hepatic and protogastric regions. Behind the cervical suture no 

 other divisional lines are visible. The upper surface of the cepha- 

 lothorax is covered with some very small granules anteriorly and 

 on the postero-lateral margins : the front, the epigastric lobes, the 

 protogastric regions, and the mesogastric area are covered with 

 minute granules, whereas the granules of the slightly prominent 

 hepatic region and of the anterior margin of the epibranchial 

 region are a little larger. The granules are nevertheless scarcely 

 visible to the naked eye. As I have already observed, some small 

 granules are also found on the postero-lateral margins, but the 

 rest of the upper surface is not granular behind the cervical 

 suture. The upper surface is everywhere minutely punctate 

 and covered with a short down, which conceals the minute granu- 

 lation of the anterior half. 



The front measures a third of the breadth of the cephalo- 

 thorax, and is considerably deflexed and slightly prominent ; as 

 in P. vespertilio, it is divided by a triangular median incision 

 into two broad, rather truncate, and slightly oblique lobes, with 

 minutely granulated anterior margins, external to which a small
