CARCINOPLAX CONFRAGOSA, new species. 



Type-locality. — Between Cebu and Bohol: Cruz Point (Bohol), S. 

 20° E., 6 miles; lat. 9° 49' 35" N.; long. 123° 45' E., 127 fathoms; 

 temperature 59° F.; March 25, 1909; station 5420, Albatross; one 

 female. 



Type.— Cat. No. 46153, U.S.N.M. 



Dimensions. — Type female, length of carapace, 38.7 mm.; width 

 of carapace between tips of last lateral spines, 45 mm. ; width between 

 outer angles of orbits, 24.3 mm.; width of front, 11.7 mm. 



Carapace very convex, inclining strongly downward anteriorly and 

 posterolaterally; regions well defined, the hepatic region depressed; 

 the granulation of the carapace is so coarse as to be visible to the 

 naked eye, especially coarse on the branchial region; antero-lateral 

 margin much shorter than the postero-lateral and armed with three 

 well-developed teeth or spines, the first tooth distant from the orbit 

 and the shortest, most dentiform and blunt-pointed, the second an 

 acute-pointed tooth, the last a conical, sharp spine directed nearly 

 forward; the three sinuses increase slightly in width from the anterior 

 to the posterior; the carapace is just as wide a little behind the last 

 teeth as it is between the tips of the last teeth. 



The front, though nearly transverse, is bilobed, each lobe slightly 

 concave and forming a small sub median tooth; a sulcus just behind 

 the margin; a depression definitely separates the front from the orbits; 

 the upper margin of the latter is transverse and furnished with bead 

 granules; the granules of the lower margin are more pointed and more 

 separated. 



The chelipeds are distinctly unequal, short and stout; surface 

 coarsely and unevenly granulate; a strong spine on the upper margin 

 of the merus and the inner angle of the carpus and a smaller spine at 

 the outer angle of the carpus. The greatest height of the larger palm 

 is just equal to its superior length; a deep sulcus above the lower 

 margin of the fixed fingers is continued back a little on the palm. 

 Fingers elongate, gaping slightly when closed, teeth uneven, a large 

 basal tooth on the larger dactyl; the brown color of the fingers occu- 

 pies about half their length on the smaller chela, and runs up farther 

 on the prehensile teeth; the brown is more extensive on the larger 

 chela. 



The legs are very hairy, especially on the margins of the last three 

 segments. The third leg is twice as long as the carapace. 



This species is not a typical Carcinoplax, as the carapace is not so 

 smoothly rounded as in other species, and the front shows two sub- 

 median teeth. 



CARCINOPLAX PURPUREA, new species. 



Type-locality. — Near Marinduque Island: Tayabas Light (outer), 

 N. 53° W., 18.7 miles; lat. 13° 42' 50" N.; long. 121° 51' 30" E.; 90
