Can this infra emarginatis j oculis usque ad angulos cantliorum externos productis; thorace lateribus 
5-spinosis ; manibus lscvissimis utrinque convexis margine superiore ct interiore obtusis. 
IIab. Japoniam. 
Carapace granulose, and without spines on the upper surface ; horns of the rostrum 
very diverging, not much longer than wide, and terminated by two teeth, which are nearly 
equal.

Orbits emarginate below, eyes prolonged as far as the external angles of the orbits, 
thorax with five spines on the sides ; hands very smooth, convex on both sides, obtuse on the 
upper and lower edges.

8. TELMESSUS, White. 
Thorace depresso, pentagonali, latero-anterioribus lateribus refiquis longioribus ; latero-posterioribus 
lateribus duobus dentibus in medio; latero-anterioribus lateribus duobus latis dentatis dcntibus inter 
exteriorem cantliorum angulum et magnam, latarn dentatam divisionem, cujus finis unum ex eminentibus 
angulis thoracis eificit. Rostrum latissimum, ex tribus latis dentibus consistens, quorum lateralis in- 
teriorem cantliorum angulum efficit. 
Pedes longissimi, compressi. 
Carapace depressed, somewhat pentagonal, the latcro-posterior sides being the longest, 
the latero-posterior sides have two teeth in the middle ; the latero-anterior sides have two 
broad, dentated teeth, between the external angle of the orbit and the strongly developed, 
wide, dentated division, the end of which forms one of the prominent angles of the carapace ; 
the beak is very wide, and is formed of three broad teeth, the lateral forming the internal 
angle of the orbit. 
Legs very long, compressed. 
This genus, described in the Proceedings of the Entomological Society, was, by mistake, 
referred to as coming near Plagmia. It, however, enters into the family Maidice ; near it 
and probably placed in the same genus is the Cancer cheirogoms, described and figured by 
Dr. Tilesius, in the Memoires de P Academic Imperiale des Sciences de St. Petersbourg 
(tome V. 1812. p. 347. Tab. VII. f. 1.), which species he tells us is taken abundantly in 
Kamschatka, at Arvatclisa, in a bay which derives its name from the abundance of the Crabs : 
the sailors of the Niva eagerly sought after the species, finding it to be very delicious as food.
