Dichogastar affinis (Mchlsn.) 
Trivandrum, 20-vi-1911. Several specimens. 
The species has previously been recorded by me from Ceylon 
(22). I stated that in the single specimen available for examina- 
tion the organs of the anterior part of the body were displaced 
one segment forwards as compared with the normal condition. It 
is possible however that this may have been apparent only, and 
due to the small size and retraction of the first segment. 
Dichogaster bolaui (Mchlsn.) subsp palmicola (Eisen). 
Datar Hill, nr. Junagadh, Kathiawar, 1-xil-1912 (S. P. Agharkar). A 
single specimen. 
From base of leaves of tall palm tree, Museum compound, Calcutta, 28- 
©vii-1908. Two specimens. 
From crown of palm tree, same place, 4-1-1yg11. Two specimens. 
From base of leaf found on so-called Sago palm, Museum compound, 
Calcutta, 9-vii-1914. Several specimens. 
It is interesting to find this Pacific subspecies in Calcutta, 
where it is also ‘‘palmicolous.”’ The specimens show a few depar- 
tures from the condition as originally described. 
The size is one of the most marked of these differences, Eisen 
(6) attributing to this form a length of 55—60 mm., while the present 
specimens varied only between 16 and 21 mm. 
The dorsal pores began in all in furrow 5/6. 
The two gizzards are in segments vii and viii; but as in D. 
malayana septum 7/8 is absent. 
The nephridia are in four rows. 
The penial setae are of two types :—(1) Length °34 mm., 
diameter 7» ; the shaft has a very slight J -shaped curve, and the 
tip is tapering, sharp and hooked. A few spines, not always con- 
fined to the concave side, stand off from the surface near the tip; 
these spines were about eight in number in one of the Kathiawar 
specimens, but were few (only about four) or entirely absent in 
one from Calcutta. (2) Length °32 mm., thickness near base 6n, 
near tip only about 2°5; the shaft shows a slight i -shaped curve ; 
the tip is expanded to form a flat oval spatula- or oar-like blade 
about 4°5» wide. There was no hint of a forking such as stated 
by Eisen for his specimens.
