no. 2067. NEW SPECIES OF CRABS— RATHBUN. 153 



fourth to sixth, inclusive, moderately convergent; the seven segments 

 distinct. 



The fronto-orbital distance of T. marginata though greater than in 

 decrescens is less than in canaliculata and piroculata, being little more 

 than half the width of the carapace; this species is the only one of the 

 genus in which the postero-lateral margins converge toward the pos- 

 terior margin, and it is also peculiar in having three antero-lateral 

 teeth. 



TYPHLOCARCINOPS ANGUSTIFRONS, new species. 



Type-locality. — Between Marinduque and Luzon: San Andreas 

 Island (W.), S. 57° W., 8.5 miles; lat. 13° 38' N.; long. 121° 58' E.; 

 50 fathoms; sft. gn. m.; April 24, 1908; station 5220, Albatross; 

 one male. 



Type.— Cat. No. 46409, U.S.N.M. 



Dimensions. — Type male, length of carapace, 11.7 mm.; width 

 of same, 15.1 mm.; fronto-orbital width, 6.6 mm.; front, 3.5 mm. 



Very close to T. marginata, but differs as follows: Size much 

 greater; fronto-orbital distance shorter; postero-lateral margins more 

 convergent; only two antero-lateral teeth, the first one in marginata 

 being represented by a slight depression in the margin, without any 

 break in the row of granules; the pigment spot on the eye is so faint 

 as to be almost indistinguishable; the merognath is not produced at 

 the outer angle. 



TYPHLOCARCINOPS OCULARIA, new species. 



Type-locality. — Between Samar and Masbate: Tubig Point, Desta- 

 cado Island, N. 49° E., 5 miles; lat. 12° 12' 35" N.; long. 124° 02' 48" 

 E.; 135 fathoms; gn. m., s.; March 13, 1909; station 5392, Alba- 

 tross; one male. 



Type.— Cat. No. 46408, U.S.N.M. 



Dimension. — Type male, length of carapace, 14 mm.; width of 

 same, 17.2 mm.; fronto-orbital width, 6.6 mm.; front, 3.6 mm.; 

 length of third leg, 31 mm. 



Covered with a short, close pubescence mixed with scanty soft hairs, 

 except the chelipeds which are bare and shining save on the mar- 

 gins; postero-lateral margins posteriorly slightly convergent; lateral 

 margins entire; median regions and cervical suture denned; margins 

 finely granulate; front arcuate, bilobed. Orbits suborbicular, eyes 

 flat, cornese well-developed. Epistome narrow, deep, edge sharp. 

 Sides of buccal cavity parallel, anterior margin arcuate; maxillipeds 

 separated by a narrow gape; outer angle of merognath rounded. 



Chelipeds massive, very unequal; margins of merus and carpus 

 fringed with hair; lower edge of propodus marginate; fingers of large 

 chela deflexed, gape narrow, tips much curved, crossing; on each
