The anterior margin of the cephalon is arched forward on each side of the middle 
line so as to form a more angular cleft than the usual crescentic curve. There are no 
spines nor any trace of the cephalic horns. Eyes well developed and lateral as usual 
though not so prominent. Of the segments of the mesosome the first three vary but 
little, the fourth is about half as long again as the first. These anterior segments all 
possess a tubercle of varying size on the epimera, and the dorsum is irregularly 
corrugated. 
The two anterior segments of the metasome are long and slender, the fusion of 
the third with the urosome is more complete than usual and marked laterally by a 
tubercular swelling of no great size. 
The urosome forms the greater part of the metasome and is rounded at the 
extremity, marked in the middle line with a slender ridge which terminates before 
the extremity in a blade-like spine. 
The first antenna is of the usual Arcturus type; the first joint is short but 
stout, having its outer margin expanded ; the two following are subequal and shorter ; 
the last is about five times the length of either of the two preceding, and provided 
throughout the greater part of its inner border with the normal sensory setae. 
The second antenna is long and slender, measuring some 57 mm. 
The first joint is very small and quite inconspicuous ; the second is longer, 
though short, the proportions of the remaining joints and flagellum are approximately 
as 2. 4. 12. 12. 21. All these joints are rather sparingly supplied with small 
inconspicuous setae. The joints of the multi-articulate flagellum are long and slender, 
each bearing a few small setae at the middle and distally. 
As there is only a single specimen the mouth organs have not been dissected. 
The maxillipeds, however, as far as can be seen in situ, presents no special features ; 
the epignath is about the average size and distinctly conical in shape. The appendage 
is rather handsomely marked with large arborescent chromatophores. 
The first appendage of the mesosome differs but little from the usual type, 
and is handsomely marked with the same large arborescent chromatophores. 
The basis is long, furnished ventrally and distally with a fringe of long setae; 
the ischium is about half the length ; the rnerus is shorter and nearly round owino- 
to its lateral extremity projecting forward as a blunt point; the carpus is rather 
cup-like with a larger ventral than dorsal surface; these three joints are well 
provided with long setse ventrally. The propodus is large but not greatly 
expanded, it is liberally fringed with long setse; the dactylus is stout, considerably 
increasing in stoutness from the base to near its distal extremity, when the dorsal 
surface becomes abruptly curved downwards to form a finger-like process, and this 
bears a stout claw and a smaller accessory ; the dorsal surface of this joint is well 
provided with long setae, more especially in the area of the “cushion.” 
The three following appendages are of the usual type ; the joints are smooth 
without spines or tubercles, but the long setae are simple and arranged in serial
