Dr. L. Orlej on Nematodes. 



cially well developed, and the lateral vessels, which branch 

 repeatedly and give off ramules in all directions, are very 

 characteristic. The lateral vessels unite in the region of the 

 oesophageal enlargement ; the strongly chitinized efferent 

 duct opens on the ventral side at about the middle of the 

 oesopliagus. Sexual organs still undeveloped. 



In many points this worm resembles Agamonema pisciuvi, 

 Rud., a form Avhich has indeed been found by Van Beneden 

 in the bat; there seem, however, to be important differences. 

 As I have as yet been only able to examine one specimen, I 

 will not describe the species as new ; on the other hand, no 

 Filaria has ever yet been found under the skin of a bat ; and 

 as this was found in a very rare species from Guatemala [JDicli- 

 durus albus)y I have thought it right to give a description 

 of it.
