 PalicKs angustus IIathiiun, Proc. Biol. Soc. Washington, vol. 11, 1897, p. 



97 (type-locality, off Santa Cruz, 117 fathoms, station 132 (not 32), 



Dlal:c; holotype. Cat. No. 2930, M.C.Z.). 



Diagnosis. — Carapace narrow, one-seventh wider than long; a 

 einuous posterior line of tubercles; three subequal antero-lateral 

 teeth. Abdomen and sternum showing prominent laminae behind

 much narrower, ratio of length to width of carapace 1 : 1.14 as 

 against 1:1.25 (smaller) to 1.39 (larger) in sica; sinuous line of 

 tubercles above posterior margin less uneven; middle suborbital 

 fissure narrower; ischium of maxilliped much wider; merus of second 

 leg short and very broad in middle; median portion of second ab- 

 dominal plate less prominent. 



Measurements. — Holotype, greatest length of carapace 9, width of 

 same 10.3 mm.
