ART. 10 EARTHWORM FAUNA OF BURMA GATES 25 



The diameter of the gizzard is nearly twice the length. The 

 calciferous gland of the left side is almost entirely in xv, the gland of 

 the right side is in xvi. The glands are large, dark red, and flattened 

 antero-posteriorly. The intestine begins in xvii. 



The last pair of hearts is in xiii. There are three pairs of com- 

 missures belonging to segments vi, vii, and viii posterior to the 

 gizzard under 8/9; anterior to the gizzard and just posterior to 4/5 

 is another pair of commissures, belonging to segment v. The dorsal 

 vessel passes through 4/5 and anteriorly. 



There is a large mass of nephridia dorso-lateral to the alimentary 

 canal in iv. 



The testes and male funnels are in x and xi, the funnels of xi 

 slightly larger than the funnels of x. The seminal vesicles are small 

 and attached to the posterior face of 11/12 at the sides of the 

 alimentary canal. The prostates are small and flattened, the 

 anterior pair in xvii and the posterior pair in 

 xix. The duct is short and nearly straight. 



The ovaries and oviduct funnels are in the 

 usual positions in xiii. The spermathecae 

 are on the parietes of viii and ix. The am- 

 pulla is in contact with the nerve cord and 

 the duct is in the body wall. There is a 

 single short diverticulum. 



Distribution. — Mandalay. 



Remarks. — The length varies from 70-100

Setal interval he may be distinctly smaller than aa or about equal

The prostates are 2-5 mm. long, and the duct is 3^-^^ mm. long. 



EUTYPHOEUS BIFOVIS, new species 



Description of the type-specimen, external characteristics (Cat. No. 

 19257, U.S.N.M.).— Length, 240 mm. Diameter, 6-8 mm. Number 

 of segments, 197. Color: Deep rich brown. 



The prostomium is prolobous. 



On segments ii to xii, inclusive, there is a deep secondary furrow, 

 posterior to the setae of the segment. On segment v there is in 

 addition a slighter furrow, posterior to the setae. On segments vi 

 to xii, inclusive, there is a deep furrow posterior to the setae. On ix 

 and X there is a slighter tertiary furrow on the anterior and posterior 

 thh'ds of the segments, while on xi and xii there is a single tertiary 

 slight furrow on the posterior third only. Segment xiii has a single 

 deep secondary furrow anterior to the setae. Posterior to the
