the median tentacle. Anal cirri proportionately somewhat shorter than in squamatus. 
Color of venter and parapodia grey; elytra at present grey over a fulvous ground. 
Setae dark amber to nearly ferruginous, darker than usual in sguamatus. A paratype 
has elytra fulvous of dilute ferruginous cast with black mottlings. 
Length, 18 mm.

Lepidonotus leius sp. nov. 
A species characterized by its rather thin, easily detached elytra which have their 
surface wholly smooth or, at most, showing a few scattered minute points; closely 
fringed along the outer margin, about the cephaloectal region, and for a short dis- 
tance along the anterior edge. Elytrophore attached cephaloectad of middle. Anterior 
and ectal margins of a typical elytron only weakly convex, the cephaloectal corner sub- 
rectangular though rounded; caudal margin strongly convex, the inner end of elytron 
like the end of an ellipse but with lower margin the more oblique. Elytra transverse 
or but little oblique, strongly overlapping in the middorsal line. Prostomium of usual 
general form. Eyes large and black, the anterior ones near middle of main region 
of prostomium, the posterior ones closer together and at caudal end. Only one tentacle, 
a lateral, retained in type. This characterized by a short cylindrical style which 
to the base of the distal swelling is scarcely longer than the basal process, and espe- 
cially by an unusually long slender tip which is as long as the rest of the style. The 
parapodium of the first segment bears two prominent setae in the usual position; 
tentacular cirri of usual form, the filiform tips long, when bent back reaching proxi- 
mad of middle of style. Notocirri also characterized by their long terminal filaments. 
Neuropodial setae light amber-colored; arranged in the usual vertically elongate patch, 
presenting a narrow dorsal half and a broader ventral one. In the ventral part of 
the patch normally four longitudinal rows of three setae each, while the narrower 
upper region shows also about four rows but with only two or one in each. The 
setae have the usual general structure. Notopodials numerous, reaching beyond distal 
end of neuropodia and sometimes nearly to middle of the neuropodial setae. In the 
type the elytra are light brown. ‘The tentacles and notocirri ringed with black as 
common. 
Length, 13 mm.; width exclusive of parapodia, 3 mm.; width to tips of setae, 
6 mm.

PHYLLODOCIDAE 
Hesperophyllum gen. nov. 
Similar in general to Notophyllum and Austrophyllum but differing especially in 
having the ventral cirrus of the second segment flattened and foliaceous and strongly 
asymmetrical. It is like Notophyllum and unlike dustrophyllum in having the first seg- 
ment dorsally reduced. 
Genotype.—H. tectum sp. nov. 
Hesperophyllum tectum sp. nov. 
The first segment dorsally reduced. Ventral tentacular cirrus of second somite 
of a thin or foliaceous and asymmetrical form. Other tentacular cirri subcylindrie, 
reduced distally to a pointed tip, that of I about half as long as the dorsals of II
