 DESCRIPTIONS OF EARTHWORMS.

Dr. R. HORST. 



IP). 

 On E u d r il u s - specimens from Surinam. 



Among the worms of our collections I met with two 

 specimens of the genus Eudrilus , kindly presented to our 

 Museum by Mr. C. J. Heering from Surinam. The genus 

 Eudrilus was named by Perrier ^), who described three species : 

 E. Lacazii (from Martinique), E. decipiens (from the An- 

 tilles) and E. peregrinus (from Rio Janeiro). Last year Mr. 

 Beddard received from New Caledonia a dozen of earthworms , 

 belonging to the same genus, which he named i?. Boyeri^). 

 The genus Eudrilus , though agreeing in many characters, 

 viz. : the arrangement of the bristles , the presence of a 

 muscular gizzard , the form of the vascular system , with 

 Eumbricus, is distinguished from it by the remarkable struc- 

 ture of its genital organs. Beddard published a careful ac- 

 count of the anatomy of these organs *), which however 

 differs in several respects from Perrier's earlier description ;
