104 Records of the Indian Museum. [VOLE.=VIEE, 
makes no mention of this feature and as only the female of 
H. gastrotrichus is known, it is not to be wondered at that Pocock 
(1900), though he refused to follow Kraepelin in regarding 
H. andersoni as a variety, did not succeed in placing it correctly. 
H. ellust, n. sp. 
Mr. C. E. Milner, of the Indian Forest Service, to whom I 
wrote in the hope of obtaining the unknown female of 4. 
sylvaticus, sent me some time ago six specimens of Hypoctonus 
collected by Mr. Ellis in the Zigon Division (Burma) under rocks 
during blasting operations in connection with a road in the 
Yoma north-east of Zigon town. ‘Three of these proved to be 
H. sylvaticus, whilst three (one male and two females) belong to 
a new species closely allied to H. andersoni. 
Description— ~. Length of carapace 8 mm., maximum breadth 
4°5 mm.; colour of body and arms dark brown above, that of legs 
pale brown ; surface of carapace smooth at sides and transversely 
rugose in middle in front of lateral eyes, finely granular through- 
out behind, incompletely grooved in the middle line ; terga of 
abdomen finely granular throughout; trochanters and femora of 
of 2—4th legs and tibiae of 4th legs finely granular above ; anterior 
half of hand finely granular below ; posterior lateral angles of Ist, 
whole of 2nd, 3rd and 4th, sides of 6—8th visible abdominal sterna 
finely and closely punctured and more or less transversely striate ; 
rest of surface of body and appendages smooth and polished or 
sparsely punctured. Arm with a conspicuous denticle dorsal to 
the coxal process which is rather long and slender; upper margin 
of trochanter entirely without teeth, anterior surface with two or 
three vertical rows of denticles, one obsolete tooth on lower 
margin; femur very sparsely punctured, rather slender, its free 
inner edge about equal to anterior margin of trochanter, one 
obsolete denticle on lower side ; tibia also very sparsely punctured, 
stem of tibial apophysis slender, lightly curved in the middle, 
expanded on the anterior edge of the upper side at first gradually 
then very abruptly into a flattened and downwardly curved blade 
which ends abruptly just before the narrow pointed extremity, lower 
edge of posterior side likewise expanded below the tip but thicker 
and the expansion nowhere abrupt ; hind margin of dorsal expansion 
not produced backwards as in H. andersoni. Hand somewhat mas- 
sive; fixed finger very broad, its inner margin strongly convex with 
the distal half very hairy, outer border finely denticulate; moveable 
finger with strongly curved and somewhat hairy basal portion, 
grooved along upper and lower and lessstrongly along outer margin, 
and followed by an abruptly defined distai portion which is 
straighter, slenderer, smoother, and sharply pointed at its extremity. 
@. Length of carapace g':0—9'5 mm., maximum width of 
same 5°0 mm. Colour, granulation, etc. as in male except for 
absence of all granules from lower surface of hand. Coxal process 
of arm shorter than in the male, with denticles above it less
