smaller size and other characters as e. g. the relative length of the anterior gastric spine and 

 the form of the scaphocerite, it more approaches the Hawaiian type of Pont. modumanuensis 

 than the two specimens from Stat. 89. 



The carapace of one of these females from Stat. 89 is 6,6 mm. long and 4,1 mm. broad, 

 the abdomen about 18 mm. long, 2,7-times as long as the carapace. The rostrum (Fig. 64^), 

 0,84 mm. long, measures only '/: tne length of the rest of the carapace, being relatively shorter 

 than in the female from Stat. 297; it reaches only to the middle of the corneae, distinctly 

 shorter than the eyes, is, like in the specimen from Stat. 297, 5-times as long as broad in 

 the middle and likewise armed with two pairs of spines. The posterior gastric spine stands at 

 the anterior sixth of the carapace, the anterior but little farther distant from the posterior than 

 from the orbital margin, but the anterior spine is much smaller than in the female from 

 Stat. 297 and measures only one fifth of the posterior, so that it may easily be overlooked. 

 For the rest the carapace resembles that of the female from Stat. 297, the supraorbital notch 

 or fissure curves likewise ontward and backward and runs thereupon as a fine suture straight 

 backward to the posterior third of the carapace ; nearly on the middle of the latter the surface 

 is slightly thickened longitudinally just above the suture, but a longitudinal keel exists here, 

 properly speaking, not nor posterior to the lateral spine. The surface of the carapace is finely 

 pubescent and longer hairs are observed on the hepatic region in front of the lateral spine and 

 just below it. From the posterior extremity of the described lateral suture a sinuated ridge or 

 keel runs obliquely forward and downward and runs to the hepatic groove below the lateral spine. 

 The abdomen agrees with that of the female from Stat. 297, but the 6 th somite is 

 rounded, presenting no shallow groove, and this groove is also wanting on the telson ; unfor- 

 tunately in one of the specimens the tip is broken off, while in the other the terminal spinules 

 are lost. The telson is pubescent and this has no doubt also been the case on the rest of 

 the abdomen. 



In the younger of the two females, of which the carapace is 6,6 mm. long, the proportion 

 between the greatest diameter of the eyes and the length of the carapace is like 1 : 8,2, in 

 the other female, of which the carapace is 6,8 mm. long and 4,2 mm. broad, it is like 1 : 7,7; 

 in both females the eyes are of a light fawn colour, with the inner border of the cornea blackish. 

 Antennular peduncle, stylocerite and flagella as in the female from Stat. 297. In the 

 larger of the two females the antennal scale (Fig. 64 h) is 3,1 mm. long, not yet half as long 

 as the carapace, and 2,5 — 2,6-times as long as broad in the middle; the scale appears thus 

 comparati vely broad er than in the female from Stat. 297, the terminal spine, long 

 0,36 mm. and 0,15 mm. broad at base, is distinctly shorter than the lamella and on the 

 outer third part of the upper surface of the scale numerous long hairs occur, which were 

 not found in the female from Stat. 297. The antennal peduncle, 1,7 mm. long and 0,36 mm. 

 thick, is a little thicker than in the specimen from Stat. 297 and extends only to the distal 

 third part of the scale. 



External maxillipedes as long as in the female from Stat. 297. 



The anterior legs (Fig. 642') reach a little beyond the tip of the antennal scale, exopodite 

 apparently wanting. A spine occurs at the far end of the upper border of the merus and a
