Length of largest specimen examined, 100 mm. 
Rostrum broadly cone-shaped, almost as long as broad at base, apex 
blunt ; carinae blunt, with six or seven small round tubercles ; surface of 
rostrum with numerous large, deep punctures ; a small tubercle at base of 
lateral carinae. 
Eyes large. Outer antennae slender, reaching to third abdominal segment, 
squame with three to five small sharp spines on outer margin, terminal spine 
stout and blunt, inner lobe broad. Interantennal spine long and broad, 
sharply pointed, lateral margins serrated. 
Carapace shorter than abdomen, as high as broad, slightly more than 
twice as long as broad ; cervical groove deeply impressed, branchio-cardiac 
grooves obsolete ; branchiostegites and anterior of carapace minutely tubercu- 
late. 
Sternal keel blunt ; first two pairs of lateral processes small and sharp, 
third pair larger, blunt and slightly grooved, posterior pair large, blunt and 
deeply grooved ; processes between fourth pereopods short and stout. 
First segment of abdomen with a small sharp spine on each lateral lobe; 
second segment with four small sharp spines along lateral margins; lateral 
margins of second to sixth abdominal segments each produced to a small 
spine; no other spines or prominences on abdomen. Telson slightly longer 
than broad, without trace of transverse suture, a small spine on each lateral 
margin near posterior margin; uropods as long as telson, each divided by a 
feeble longitudinal median carina, ending in a spine almost on posterior 
margin ; inner rami with a small spine on lateral margin near posterior 
margin ; transverse suture of outer rami fringed by several small sharp spines; 
semi-membranous below transverse suture. Lobes at base of uropods without 
spines. 
Great chelae short and stout ; propodus twice as long as broad, with 
numerous small tubercles and deep punctures, upper margin with a single 
row of blunt tubercles, lower margin with a double row of small blunt 
tubercles, cutting edge with five small tubercles, margined on the outer side 
by a row of seven or eight small blunt tubercles ; dactylus stout, cutting edge 
with three large and four small tubercles, margined on the outer side by a row 
of seven or eight small blunt tubercles; upper margin with two longitudinal 
carinae, each with five or six small round tubercles; carpus with one large 
and four or five small sharp spines on upper margin; merus with a row of 
very small sharp spines on upper margin.
