as the two precedin<^- segments combined, somewhat narrower tlian fifth segment, and posteriorly 

 emarginate. — Uropods (figs. 2 a and 2 h) sHglitly sliorter than tlie alidomen; pednncle about two and 

 a lialf times as long as broad; endopod very long witli thirteen joint.s, tlie first joint conspicuously 

 thicker than the second and third and as long as these two combined; cxopod verv small, two-jointed, 

 with the proximal joint shorter than the distal.

Remarks. Though new species of this familv as a rule ought not to be founded on adult 

 males, I venture to establish a new species on the specimen described, because it is not only charac- 

 teristic but very mnch larger than any sjjecimen of Tauaidie hitherto captured. The animal when 

 hauled u]i from tlie sea was quite white. 



Occurrence. The "Ingolf" has taken this species at a single station.

Female. The bod\- (fig. 5a) about six times as long as broad. — Carapace onl\' a little 

 longer than the two anterior thoracic segments combined, a little longer than broad, anteriorlv not 

 fulh' half as broad as somewhat before the posterior margin (fig. 5 b). 



The e\e-lobes are considerabh' produced, distally not angular l)ut rounded (fig. 5CI; the eyes 

 are moderately large, black, but the black pigment renders it impossible to count the ocelli, a couple 

 of which are seen at the hind margin of the black spot. — The antennuke (figs. 5 a and 5 c) are a 

 little shorter than the carapace, somewhat slender; first joint somewhat longer than the two others 

 combined, almost four times as long as deep; third joint about twice as long as the second. — An- 

 tennae somewhat slender; fourth joint (formed by fusion of fourth and fifth joints) only as long as the 

 two preceding joints combined. 



The chelipeds (fig. 5c) are somewhat robust; the carpus is almost twice as long as deeji. The 

 chela is somewhat longer tlian the carpus and somewhat more than twice as long as broad; the 

 mo\ablc finger is much shorter than the hand; the fixed finger ifig. ^d) is somewhat expanded on 

 the incisive side with about three low protuberances and near the end rather broad and distalh' rect- 

 angular, while the very short ai:>ical part of the finger is slender and markeil off from the inner 

 expansion. 



vSecond pair of legs (fig. 5 c) with a ver\- long seta from the upper distal angle of fifth joint; 

 sixth joint about as long as fifth and fourth joints combined and a little shorter than seventh joint 

 with claw; scvenlh joint a little shorter than the claw. Tiiird \rA\x of legs (fig. 5 e) have tlie .seventh
