Specific Character. — Body comparatively short and 
thickset, more particularly in female; dorsal face dense], \ 
armed with acute spikes, some of which are characterized 
by considerable length; the 2 lust body-segments quite short, 
each furnished with only 4 spikes. Eyes small, punctili- 
form. First pair of antennas in male much more elongate 
than in female; last joint of peduncle longer than 1st, fla- 
gellum shorter than peduncle; 2ud pair armed posteriorly 
with fascicles of strong bristles, in female longer than ped- 
uncle of 1st pair. Second pair of legs in female of moderate 
size, with band oval, and posteriorly having 4 small denti- 
form prolations, the 3 outermost close together, arid separated 
by a rather wide interspace from the 4th; in male much 
ni0 re powerfully developed, with hand remarkably large, 
oblong, densely filiate along both margins, and exhibiting 
posteriorly 2 deep incisions, defined by lanceolate lappets, 
the median the largest. Posterior pairs of legs of usual 
appearance. Colour a uniform greyish-white. Length 14— 
20 raw .

Remarks. — On a former occasion, I recorded this 
characteristic species under a new name, viz. horrida, to 
prevent its being confounded with Stimpson s JEgma spi- 
nosissima. Meanwhile, as the latter is identical with the 
form Caprella spinifera, described somewhat earlier by Bell, 
and must, therefore, bear the last-mentioned specific desig- 
nation I see no reason for suggesting any change m the 
name proposed by Norman for the species treated of here: 
it, is now retained. 
Description of the Female. - The body (see PI. 
VIII fig 4)j in comparison with the other species 
n lls ’is unusually short and thickset in form, as also, 
the more particularly in ovigerous females, somewhat 
pressed, especially throughout the medial part The 
loie dorsal face of the animal is densely beset with 
ute upturned spikes, some distinguished by very con sider- 
le Jen Ah. The latter are arranged in pairs along the 
„di an line, in such manner that one or two pairs occur 
“ each segment. Moreover, a number of lateral-directed 
ikes maj & be also observed, of which in particular 2, 
st above the marsupium, and issuing at the base of the 
■anchial scales, are the most conspicuous. 
The head is very small, obtuse anteriorly, and above, 
common with the rest of the dorsal face, densely beset 
tb spikes 2 of which are characterized by considerable
