In this species, as in MZ. marginata (Elasmonotus marginatus Hend.), M. 
edwardsti (Elasmonotus edwards: W.-M.), etc., the lateral margins of the cara- 
pace are produced into sharp crests which overhang the sides of the body. 
The upper surface of the carapace is rather flat, and is clothed with a close, 
short pubescence ; the sides of the carapace are nearly parallel. The rostrum 
is long, acute, nearly horizontal, the upper surface roof-shaped. There is a 
prominent tooth at the external orbital angle, and another smaller one at the 
antero-external angle of the carapace; otherwise the carapace is unarmed. 
The eye-stalks are immovable, their proximal ends being anchylosed with the 
ocular segment; they project forward far beyond the eye, forming sharp 
horns one half as long as the rostrum; seen from above, the eye-stalks 
appear like lateral spines of the rostrum ; they are pubescent, like the cara- 
pace. The antenne are shorter than the body; their basal segments are armed 
with a prominent triangular tooth on the anterior margin of the lower side, 
while the second segments are similarly equipped with a tooth on the outer 
side. The chelipeds are short and pubescent; there is a prominent spine at 
the distal superior angle of the ischium, and a tooth near the distal end of 
the internal margin; five or six teeth along the superior margin of the merus, 
and one on each side of the distal end of the same segment ; the carpus bears 
a superior tooth near the proximal end, together with three teeth on the distal 
margin; the chela is short and thick, the hand devoid of teeth or spines; the 
fingers are very short and thick, meeting one another only at their spoon- 
shaped denticulated tips; there is a rounded tubercle at the base of the inner 
margin of the immovable finger; the outer margin of this finger is denticu- 
lated. Ambulatory limbs: five to seven spines on the superior and external 
inferior margin of the meri (those on the superior margin the largest) ; 
upper edge of carpus three to four-spined ; propodites unarmed ; inner mar- 
gin of dactyli denticulated. Abdomen without spines, somewhat tomentose.
