Two young, 11 ram. long and less, have proportionally much longer spines, each spine of the 
carapace being about one-fifth as long as the width of the carapace measured in front of the spine; the 
arm spine is stouter and as long as or longer than that of the carapace. The two teeth of the posterior 
margin are longer than in the adult, and the tubercles of the dorsal surface much stronger. 
Mursia spinimanus, sp. nov. 
(PI. xvi, fig. 1.) 
Closely related to M. bicristimana Alcock (conf. Deep-Sea Brachyura Investigator, 23, pi. m, 
fig. 3). It differs as follows: 
The posterior margin is armed with three, instead of two, blunt denticles. 
The crest of the arm is three-spined, the .innermost very small, the outermost longer than in M. 
bicristimana, and three-fourths as long as t the spine of the carapace, in the 
young fully as long as the latter. 
Lower margin of hand armed with slender spines directed more 
obliquely than in M. curtispina Miers (Challenger Kept., pi. xxiv, fig. 2). 
The inner surface has a band of felt-like hair above the lower margin. 
Thumb longer than in M. bicristimana, exceeding its greatest width. 
The three lobes of the carina of the second abdominal segment are more 
nearly equal, the median only slightly wider than the lateral. 
In the tridentate posterior margin, spinose inferior margin of hand, 
and elongate thumb, this species approaches M. curtispina, from which it is 
at once separated by the wider carapace, broader movable finger, and dif- 
ferent shape of teeth on upper margin of palm. 
Dimensions. — Male type, length 36 mm., width measured just in front 
of spines 46.1 mm., width between tips of spines 65.7 mm. 
Distribution. — South coast of Oahu Island, 52 to 238 fathoms, stations 
3810 and 3811; south coast of Molokai Island, 92 to 212 fathoms, stations 3838 and 3855; Pailolo 
Channel, 123 to 141 fathoms, stations 3856 (type locality) and 4104. Cat. No. of type, 29922. 
I agree with Maj. Alcock that Platymera should be united with Mursia.

Distribution. — South coast of Molokai Island, 23 to 24 fathoms, station 3847; Auau Channel,- 32 to 
37 fathoms, station 3873. 
These specimens are a little smaller than the type; the immature female shows-the unevenness of 
the surface more distinctly than the mature female. Length of the latter 3.7 mm., width 5.6 mm.
