PECTINARIA Lam. 

 (Subgenus LAGIS Mgrn.) 



Pectinaria (Lagis) dubia n. sp. 



PL. X, FIGS. 140-144. 



Two specimens were found which seem to belong to 

 Malmgren's genus or subgenus Lagis. Through some 

 carelessness I failed to make notes on them when they 

 were collected. Their present condition does not admit 

 of specific description, except as regards the setse. These, 

 in some respects are peculiar; there are eight paleolse on 

 each side, flattened, slightly curved to near the end, ter- 

 minating in a stout hook (f. 140). The dorsal setae are of 

 two forms : one, simple, acuminate (f. 141) ; the other, 

 also simple, but curved slightly, and with a large, well 

 defined projection or knee at about the outer fourth (f. 

 142), beyond which the edge is divided into numerous 

 fine, hair-like, projections by oblique incisions. Ventral 

 uncini (f. 143) with seven long, sharp teeth. 



Spinulse of the scapha (setae of the caudal process) in 

 two series, ten in each ; of which seven are of the form a, 

 b, f. 144, and three correspond to c, d, e. 



Length of one specimen 6""" ; of the other 4™™.
