As to the internai anatomy it could be recognized, that the 6th., 

 7th., 8th and 9th septum are very thick and muscular, fitting like 

 funnels one into another, and totally inclosing the oesophagus. The 

 10th. septum is absent, or is displaced to the limit between segment 

 XI and XII. 



The gizzard commences in segment XVII and consists of eight 

 divisions; in Desmogaster doriae there are ten gizzards; the first of 

 them lying in segment XX. The prostate-glands represent long, 

 tubular organs , tapering towards their external extremity ; their distal 

 portion however is again broader and has a somewhat triangular shape. 

 It seems to me, that the prostate-glands of our specimen differ in 

 shape from those of D. doriae and I also believe to have observed , that 

 the vasa deferentia do not open at the top of those glands, as des- 

 cribed by Rosa. 



Though only a single specimen was collected, it furnishes a new 

 point of agreement between the earthworm-fauna of the Indian con- 

 tinent and the Malay Archipelago. 



Uroohaetidae. 



Pontoscolex Schmarda. 

 (Urochaeta Perrier). 



By his recent examination of the type-specimens of Lumbricina, collec- 

 ted and described by Schmarda, Beddard 1 ) has clearly shown , that the 

 genus Pontoscolex 2 ) is identical with Perrier's genus Urochaeta. Now 

 Perrier himself in his first communication on Urochaeta 3 ) has already 

 pointed out the close resemblance of the two genera; as however Schmarda 

 stated, that Pontoscolex possesses fourteen series of setae, alternating in 

 the successive segments, instead of sixteen, Perrier was quite right 

 in believing the two genera to be different. However according to 

 Beddard's investigation of Pontoscolex, Schmarda's enumeration was 

 inaccurate, there being eight setae in each segment; the name Uro- 

 chaeta therefore ought to be cancelled. 



Pontoscolex appears to have a very wide geographical distribution,
