Genus Scalpellopsis nov. 
Capitulum with 9 or 1 1 plates: rostrum, and rostral latus absent, 
inframedian latus rudimentary, carinal latus well developed. Upper 
latus interposed between carina, tergum, and scutum. Peduncle 
with scales. — Male absent. 
It is not without hesitation that I introduce this new genus. It 
is closely allied to Scalpellum, and we might feel inclined to con- 
sider it a subgenus of the latter. Nevertheless the great number 
of species of that genus, and the dissatisfactory systematic group- 
ings of it made me prefer, at all events provisionally, to introduce 
a new genus for the species described below. The great reductions 
in the lower row of latera give it an aspect which differs strik- 
ingly from the true Scalpellum. 
Scalpellopsis striatociliata n. sp. 
Near Jolo; 20 to 30 fathoms, on hydroids. 19/III 14. Several specimens. 
Valves of the capitulum eleven, covered by a chitinous mem- 
brane. Carina simply bent with apical umbo. Terga triangular, scuta 
quadrangular with apical umbones. Upper latus large, quadrangular. 
Carinal latus large, triangular, pointed towards the rudimentary 
inframedian latus. — Scales of the peduncle large, in four longi¬ 
tudinal rows. Cuticle of the capitulum with transverse rows of long 
hairs. Peduncle with a broad, anterior, longitudinal furrow. • 
The capitulum (Fig. 11) is broad; its width is about two 
thirds of its height. It is covered by a pellucid, hairy, chitinous 
membrane, and the transversal rows of hairs lend a peculiar aspect 
to the species. The rather long hairs are placed in four or more 
transverse rows on the terga, scuta, and carina, two or three on 
the carinal latus, but no distinet rows were observed on the upper 
latus; at the lower part of this plate, between the plate, the scutum, 
and the carinal latus a row of hairs is seen. The interspaces be¬ 
tween the capitulum plates are very narrow, but of a dark brown- 
ish hue. 
Scutum is quadrangular with an almost quite straight occlud- 
ent margin; the umbo is apical. The apical part slightly overlaps
