MUNIDOPSIS LATIROSTRIS. 99 
The rostrum is triangular, blunt at the apex, bent strongly downward, and 
slightly cariate above. The antero-lateral angle is rounded, and a rounded 
lobe projects from the anterior margin above the base of the antenna. The 
abdomen is smooth, naked, devoid of spines and ridges; the abdominal pleuree 
are rounded. Ocular peduncle free, spineless. The peduncle of the antenna 
is also destitute of spines; the flagellum is wanting in the only specimen 
obtained. The chelipeds are also missing. The ambulatory appendages are 
smooth, unarmed; the dactyli long (equal to the propodites in length), 
slightly curved, acute at the tips. The appendages of the third, fourth, 
and fifth abdominal segments are simple and rudimentary. The merus of 
the third maxillipeds is short, its antero-internal margin three-toothed ; the 
palpus of this appendage is nearly as long as the merus and ischium 
combined. 
Length 12 mm. ; carapace, 6 mm.; breadth, 4 mm. 
Station 3354. 322 fathoms. 1 male. 
This species nearly resembles J. polita ( Anoplonotus politus Smith), but the 
carapace of the former is longer and narrower, the rostrum is curved more 
strongly downward, and the propodites of the ambulatory limbs are much 
shorter in proportion to the dactyli.

In his first description of this species Prof. Henderson describes the 
eye-stalks as fused with the sides of the rostrum, while in his final report he 
states that they are slightly movable. In the “ Albatross” specimens they 
are firmly soldered to the rostrum. Henderson also says that the ambulatory 
limbs have a few short blunt spines on the anterior margin of the meri, 
carpi, and propodites. In the ‘ Albatross’’ specimens the spines of the meri 
are on the posterior margin of the joint, but these specimens agree so well with 
Henderson’s description in other respects that I do not doubt that they be- 
’ 
long to the same species. The unique “ Challenger” specimen was obtained 
between Papua and the Admiralty Islands at a depth of 1070 fathoms.
