least some species of Liobunum. The procursus maxillaris in- 
ternus is well developed and two-branched in the Gagrelline and 
Lnobunum, while in Phalangium it is a slightly marked projection. 
Tt is thus evident that the limitations of the two subfamilies 
Gagrelline and Phalangiine fluctuate, and that Liobunum forms 
a connecting-link between the two. 
Since I am not the most competent person to judge where the 
limits are to be drawn, and since Drs. Sérensen and Hansen have 
called my attention to several of the aforenamed facts, which 
make the subfamily of the Gagrelline an unnatural one, I would 
refer to the forthcoming paper, in which they record these and 
other important results of their investigations. 
ON THE SYSTEMATIC AND SEXUAL CHARACTERS. 
The shape of the cephalothorax varies but little. The last 
segment is always separated by deep articulations both from 
the rest of the cephalothorax and from the abdomen. The 
enultimate segment may be well marked, butit is never 
limited by an articulation in front. The tubercle is placed 
nearer or farther from the abdomen in relation to the development 
of the aforenamed segments, and the segments of the scutum 
are marked by transverse grooves on each side. The scutum is 
either unarmed or provided with a spine or tubercle. There is 
ordinarily one spine on the second segment; more rarely there 
is one on the first as well. In Scotomenia there is a tubercle on 
the first. The number of the spies is a very characteristic 
specific feature, but their generic value is relatively slight, and 
it seems to me impossible to found good genera upon their 
development, as Thorell has done. Yo this subject, however, I 
shall return. Their number varies also according to the species. 
In Zaleptus minutus, n. sp., there is occasionally an abdominal 
tubercle. Gagrella imperator, n. sp., has either two long or one 
long and one short spine. 
The granulation of the body in variable, but of some systematic 
value. The body is very seldom pitted as it is in G. sordidata, 
Th., and ordinarily it is more or less granular. The granules 
are more or less crowded, larger or smaller, and flattish. Dorsally 
the scutum is almost always well granulated, the other parts 
more or less so; while the free ventral segments, with the 
exception of the lateral parts and the articulations, are generally 
smooth.
