60 DR. J. G. DE MAN ON THE PODOPHTHALMOUS 
The following is the description of the largest specimen, a 
female, found at Elphinstone Island. 
In its outer appearance P. Andersoni somewhat resembles the 
common Indian P. vespertilio, Fabr., but it is of smaller size 
and much less hairy. The cephalothorax is about once anda 
halt 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 1s much 
declivous anteriorly towards the front, and also somewhat towards 
the lateral margins. 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. AsI havealready 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
