ME. F. E. BEDDAED ON ANNELIDS 



Eeport on Annelids from the Mergui Archipelago, collected for 

 the Trustees of the Indian Museum, Calcutta, by Dr. John 

 Anderson, F.B.S., Superintendent of the Museum. By

 John Andeeson, F.R.S., F.L.S.)

Eupompe indica, n. sp. (Plate XXI. figs. 1 & 3.) 



A single specimen of an Annelid contained in the collection 

 appears to belong to an undescribed species, which I would refer 

 to the genus Eupompe. 



It presents numerous points of agreement with Panthalis mela- 

 nonotus and with P. nigromaculata, already known through 

 Grube's researches* to inhabit the shores of the Philippine 

 Islands ; it agrees, in fact, with those two species rather more 

 closely than with Eupompe Grubei, the only describedf species of 

 its own genus. 



A careful study of this species and of the description of other 

 species published by KmbergJ and Grube§ has convinced me 

 that there are no grounds for distinguishing the genera Eupompe 

 and Panthalis ; and as the former name appears first in his 

 descriptions, I retain it as having the priority. 



In comparing Kinberg's diagnoses of the genera Eupompe and 

 Panthalis (which I need not quote in full), I find that the only 

 points of difference concern the protrusible pharynx and the ar- 

 rangement of the elytra. The diagnosis of Panthalis contains a 

 statement with respect to the ventral cirri which is not found in 

 the diagnosis of Eupompe. A comparison of the figures of these 

 structures, however {loc. cit. pi. vii. figs. 34 F, 35 F, and 34 F', 

 851"), shows that there is hardly sufficient difference in their 

 shape and position whereon to found a specific, let alone a generic, 

 dial incl ion. The elytra in Eupompe are flat, not meeting in the 

 dorsal middle line anteriorly, but covering the dorsal surface 

 posteriorly; the elytra in Panthalis are described as being nu- 

 merous, the anterior series flat, the posterior bell-shaped ; the first
