140 THE VOYAGE OF H.M.S. CHALLENGER. 



slender and moderately spiny, with the fingers narrow, scarcely equal in length to the 

 palm, and in contact throughout. The ambulatory limbs are slightly flattened, and 

 pubescent above, the meral joints being in addition somewhat scaly ; the dactyli are 

 moderately curved towards their apices, and a few horny spinules are present on the 

 posterior margin. 



The eyes are of moderate size and slightly flattened, while a series of long and pro- 

 minent hairy "lashes" extend over the cornese from both the upper and lower margins. 

 The antennal spine is of moderate length, not exceeding the second joint of the peduncle, 

 which last is armed with two prominent spines on its inner border, and one on the outer. 

 The ischium and merus of the external maxillipedes are clothed externally with pubescent 

 scales, the inner margin of the former joint terminates distally in a short obtuse spine, 

 while the latter possesses three spines on its inner margin, one being situated at the distal 

 end, another near the middle, and a third of smaller size between the two, in addition to 

 an acute spine of small size at the distal end of the outer margin. 



The second abdominal segment bears from six to eight spinules on the anterior dorsal 

 margin. The transverse strise are smooth and polished, though fringed with hairs ; on 

 the sixth segment they are somewhat broken up. 



This species is closely allied to Munida militaris, Henderson, from which it may be 

 distinguished by the presence of a second pair of gastric spines, and the pronounced 

 " lashes " overhanging the cornese. I have named it after Mr. W. A. Haswell, in recogni- 

 tion of the assistance I have derived from his work on the Australian Crustacea. 



Breadth of carapace (of an adult male) 9 mm., length of body 25 mm., of carapace 

 11 mm., of rostrum 6 mm., of first ambulatory leg 28 mm. 



Habitat. — Station 163A, ofi" Twofold Bay, Australia; depth, 150 fathoms; bottom, 

 green mud. One male and three young specimens.

Characters. — The rostrum is more than half the length of the carapace, and three 

 times the length of the supraorbital spines ; all three are slightly upturned, and the 

 rostrum is somewhat flattened from side to side. The carapace is crossed by fairly 

 numerous and prominent granulated pubescent striae ; the gastric area is moderately 

 convex, and is armed in front with a transverse row of spinules — ten or twelve in 

 number — of which only the two placed behind the supraorbitals attain any considerable 

 size ; the posterior pai-t of the gastric area is mapped out as an oval patch, circumscribed 

 in front by a line passing between the two cervical grooves, and posteriorly by the 

 grooves themselves at the point where they unite ; the cardiac area is not defined, and it, 

 as well as the remaining surface of the carapace, is unarmed. The lateral border of the
