36 Records of the Indian Museum. [Vor. VII, 
‘* The worms ‘ from a small stream’ [Sita Nullah, on the lower 
slopes of the hill] belong to two species, the larger being a ‘ Glyphi- 
drilus sp.’ (perhaps the same as that from the Himalaya, which was 
not determinable) and two specimens of an Ocnerodrilid with one 
gizzard, viz., a Gordiodrilus or a Kerria. ‘The worms ‘ from mud at — 
the edge of small spring’ [alt. ca. 4,000 feet] belong to Perionyx or 
Perionychella (probably Perionyx excavatus, E., Perr., which is so 
often found immature and so widely distributed).” 
At the time Dr. Michaelsen wrote this note only one species of 
Microchaetinae had been recorded from India, namely an indeter- 
minable young form of Glyphidrilus from the Simla Himalayas. 
More recently he has described the same or an allied species, 
from mature specimens taken in the plains of Travancore, under 
the name G. annandalei 
CRUSTACEA.

There are numerous specimens in our collection obtained on 
Parésnath by Stoliczka, and I found several myself in the small 
spring (alt. ca. 4,000 feet) to which allusion has already been 
made. ‘They were unusually small although apparently adult. 
P. jacquemontii is widely distributed in Peninsular India but 
appears to be rather commoner in the western and the southern 
districts than in Bengal. 
Family PALAEMONIDAE. 
Palaemon (Brachycarpus), sp. 
In a jungle stream running down the north slope of the hill 
and known as Sita Nullah I found, at an altitude of about 2,000 
feet, numerous specimens of a small prawn belonging to the 
subgenus indicated. It is remarkable for its dark green, almost 
black colour and has the thick-set appearance often possessed 
by prawns of the genus from mountain streams. The species 
is probably undescribed as yet but, should this prove to be the 
case, will be described later by Mr. S. W. Kemp. It appears 
to differ considerably from the species common at similar alti- 
tudes in jungle streams in the Darjiling district, but may be 
identical with one that occurs in the R. Tista at Jalpaiguri. 
A few terrestrial isopods were also obtained but have not 
been identified.
