LitosTROPHUS, gen. nov. 
Posterior gonopods broadly in contact at median line ; 
coxal division at right angles to the telopodite, very broad, 
disto-proximally broadest at middle line. Telopodite a broad 
plate as usual, curving disto-mesad; excavated below disto- 
mesal corner, the latter projecting as an acute angle, while 
below excavation is a rather long, slender, styliform process. 
The median plate of the anterior gonopods has a very charac- 
teristic form, the distal undivided division being narrow and 
long, equalling the coxal plate of the anterior gonopods in 
length; proximal angles produced, as usual, into slender 
arms, each of which curves against the base of the gonopod, 
but ends distinctly on the middle of the anterior side of the 
latter, where it joins or lies over the chitinous bar, which 
curves about to the caudal side of the gonopod, the outer 
lobe not projecting as a lobe into the mesal area between 
the arms. Coxal piece elongate, simply and symmetrically 
narrowed distad. The distal or posterior segment also a 
simple elongate symmetrically rounded and curving caudad 
distally. 
Antenne short and thick, the basal part of each lying in 
a deep excavation or groove below the eye. Labral sinus 
large, obtusely angular, occupied by two large rounded 
teeth, with an obsolete much smaller one on each side. 
Collum of normal size, strongly narrowed down each side. 
Repugnatorial pores on the prozonites. 
In the male there are prominent tarsal pads on all the 
legs, including the most posterior. 
Anal scutum produced into a cauda cousiderably ex- 
ceeding the valves. 
senotype, L. segregatus, sp. nu. 
Titostrophus segregatus, sp. 1. 
Because of long preservation and having been allowed to 
dry, the type does not show with certainty the original 
coloration. At present it is testaceous, with the posterior 
borders of the segments much darker. 
Eyes subtriangular with the caudally placed base strongly 
convex, the sides straight, and the anterior angle or apex
