SYNONYMY OF PHERECARDIA LOBATA. 17 
NOTE IV. 
ON THE SYNONYMY OF 
PHERECARDIA LOBATA HORST 
BY 
Dr. R. HORST. 
(With 1 text-figure). 
In my paper »Contributions towards the knowledge of 
the Annelida polychaeta, 1: Amphinomidae’’!) I was the first 
to describe the genus Pherecardia, characterized by having 
a caruncle, composed of a median heart-shaped axis, that 
bears on each side several (7) folded lobes of a lamelliform 
shape and directed backward. A tuft of short cylindrical 
branchial filaments occurs on each body-ring and the bristles 
of the ventral fascicles are not bifurcated, but provided 
with a hooklike bend tip, whereas the dorsal ones are 
partly capillary, partly stout, with serrations, having the 
shape of an Y. It was based on a badly preserved speci- 
men, of which the locality was unknown, but in 1902 
Collin mentioned it in his »Verzeichniss der von Prof. 
Semon bei Amboina und Thursday Island gesammelten 
Polychiten” *), however without giving any peculiarity 
about the specimen he examined.

Unfortunately this paper was overlooked by several authors (Gravier, Fischli, 
Potts a o.) though it was duly referred by Jeffrey Bell in the Zoological 
Record for 1886, Vermes, pp. 11 and 14.
