terior half of annulus 4, a pair of small eyes on either side of the 

 median line and a pair of much larger eyes placed about midway 

 between the median eye and the lateral margin. The opening of 

 the pigment-cup of the median eyes is directed forward, that of 

 the lateral eyes forward and slightty toward the side. The re- 

 maining pair is found on annulus 5 just behind the lateral eyes 

 of the preceding annulus. The pigment-cup of this pair is directed 

 backward and a little laterally. The two lateral eyes of either side 

 are placed so closely together, that their pigment cups touch each 

 other with their bottom, presenting the form of X in surface 

 views. Very possibly the eyes which appear to be placed in 

 annulus 5 belong in reality to annulus 6, the pigment cup having 

 been displaced forward. So far as I am aware, there is no Glossi- 

 phonid hitherto known which presents a similar arrangement of 

 eyes. 



The genital openings are separated by two rings. The male 

 pore lies between annuli 24 and 25, the female pore between 

 26 and 27. Both openings are small and inconspicuous. The 

 clitellum could not be distinguished in any of the specimens 



The nephridial pores were invisible in surface views. By a 

 careful study of longitudinal sections I was enabled to locate them 



at the usual position,

Somites xxii-xxvii with sucker : X30. The colour of the 



specimens preserved in

 animal having been spotted or mottled during life. 



Internal anatomy. The proboscis is very long and slender. 

 A short oesophagus connects the base of the proboscis with the 

 crop, which extends over six somites and is provided with as 

 many pairs of diverticula. The latter are all simple except those 

 of the last pair which extend backward and are provided with 

 three short branches directed toward the side. The stomach bears 

 four pairs of simple tubular diverticula, of which the first two 

 pairs are directed forward, the last pair backward, while the 

 third pair lies about at right angles to the long axis of the 

 body. 



There are six pairs of testes placed alternately with the crop 

 diverticula, the first pair being in front of the most anterior of 

 the latter. The ovaries are, as usual, a pair of simple sacs ex- 

 tending back along the sides of the ventral nerve chain.
