 drews.— No. XLIII. By Prof. M'Intosh, M.D., LL.D., 



Recent Additions to the British Marine Polychata. 



Since the publication of the earlier parts of the 'Mono- 

 graph of the British Marine Polycheets ' was commenced 

 (nearly fift^' years ago) many additions have been made, and 

 some of these have already been described in the 'Annals 

 and Magazine of Natural History.' ' Others will be indicated 

 in the following notes. 



Of the Euphrosynidse, a post-larval form was procured

Anteriorly, in the microscopic preparation, the head con-

 dimpled in front, narrower behind, and with a more deeply 

 stained clavate band along each side, at the anterior end of 

 which is a minute dark eye. This shield-shaped region is 

 minutely streaked and dotted, apparently from the minute 



* The former name of no. 82, Gaspnrritiia lobulata (Sommf.), bad 

 to be changed for this new one. 



t In addition to this form, there exists undoubtedly a forma centro- 

 leuca (Mass.), Mer., which I have observed in Italy, distinct from the 

 forma mesoleuca by the absence of cc-nceutric zones of yellow and white 

 coloration on the thallus.
