PECTINARIA Lam. 
(Subgenus LAQIS Mgrn.) 
Pectinaria (Lagis) dubia n. sp. 
PL. X, FIGS. 140-144. 
Two specimens were found wLich 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 uot admit 
of specific description, except as regards the setae. These, 
in some respects are peculiar; there are eight paleolae on 
each side, flattened, slightly curved to near the end, ter- 
minating in a stout hook (f. 140). The dorsal setse 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 (setse 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"".
