lias the median lobe lens well defined and the Ketae of the ventral 
border ai'e not very numerous. The outer limit of the setae on tlie 
left side is defined by a short stout s])ine wliieh is, perhaps, ])resent 
also in Neoiiiphai’pus spcnccri and Nipltarpnn pulchclJus |(T. bayee s

Hayee mahes no mention of it. 1 find a somewhat similar strueture 
ill N. branchiaUs. (19114, PI. 10, Vig. L.ll). .Mandibular ])rocesses 
are well develo])ed. 
Tlie left mandible (Ph A'llt. Fi^-. 4) is miicli as in NipharpKH 
pulchellus (1900, Ph 10, Fig- 4), but tlie accessory dentate edge is 
more wi<lely se])arated from the ])riucij)al cutting edge. The rif/lit 
mandible (Ph VIII. Pig. 4a) a])proximates much more nearly to the 
condition figured by Sayce for Nconipbarf/us spcnccri (1900a, Ih 40^ 
Pig ill-.). 
Tlie first maxilla (Ph VIII. Pig. o) somewhat resembles that of 
Nconijdiargvs branchiaUs (1924, Ph 10, Fig. All) and N. ihomsoni 
(189d, Ph 6, Fig. 5). The small rounded inner lobe is crowned by a 
single slight, scarcely iilumose seta set in a general fringe of deli- 
cate setae. The outer idates are relatively larger and are armed 
a.pically with 8 (or 9) strongly chitinised jiectijiate setae 
with an innermost simjile seta. The })alp. which differs on 
opposite sides, is broader relatively (as comjiared with N. 
branchiaUs.) On the one side it bears terminally 0 sliort conical 
spines, while on the other (Ph AMII. Pig. da) these are replaced by 
five stiff setae sparsely plumose,
