278 Mr. C. Spence Bate on the 



New Zealand, at a deptli of 520 fathoms, on hard ground, 

 where the sea-temperature at the bottom was 6° C 



A fine specimen was also taken 2000 miles from the last 

 place, in lat. 2° 33' S., and long. 144° 4' E., north of New 

 Guinea, at a depth of 1070 fathoms, on Glohigerina-oozQj 

 with a bottom-temperature of 2°'l C. 



Polycheles baccatus, n. sp. 



Lateral margins of the carapace subparallel ; anterior divi- 

 sion armed with twelve teeth, median with five, and posterior 

 with many, extending to the posterior margin ; anterior margin 

 serrated and armed with teeth on the inner side of the antero- 

 lateral angle ; central ridge projected into a rostriform tooth 

 supported by two small teeth ; median dorsal ridge without 

 teeth or spines ; but a few bead-like points fringe the posterior 

 part of the median line and the posterior margin. Pleon 

 carinatedon each of the four anterior somites and projected into 

 an anteriorly pointed tooth. Eye lodged in a deep notch in 

 the antero-dorsal surface of the carapace. Meros of the first 

 pair of pereiopoda smooth, except a small tooth on the outer 

 distal angle. 



This species was taken in lat. 19° 10' S., long. 179° 40' E., 

 near the Fiji Islands, at a depth of 310-315 fathoms, on a 

 bottom that is marked " r.c." in the plans. 



PentacheJes difiers from Polycheles in having the last pair 

 of pereiopoda always more or less perfectly chelate. 



Pentacheles Iccvis, n. sp. 



Carapace ovate ; lateral margins serrated conspicuously at 

 the anterior extremity, the serration gradually decreasing in 

 importance posteriorly ; frontal surface having the inner 

 canthus of the orbit produced to a prominent tooth, and 

 two rostral teeth in the median line, behind which, on the 

 median ridge, there are two small teeth ; the rest of the 

 dorsal surface is smooth. Pleon slightly carinated, but not 

 very distinctly so. Posterior pair of pereiopoda imperfectly 

 chelate. 



Taken in lat. 4° 33' N., long. 127° 6' E., at a depth of 

 500 fathoms, on a bottom of Globigerina-oozQ with a tempera- 

 ture of 5°'3 C, south of the Philippine Islands.
