PBELIMINARY EEFORT. 69 



Station 265, lat. 12' 42' N., long. 152' 01' W.. in 2900 fathoms, obtained 

 only one specimen of Gonostoma. At Station 270, lat. 2" 34' N., long. 

 149 09' W., two species of deep-sea Keratosa were obtained in 2925 

 fathom.?, Tahiti distant about 1200 miles. At Station 271, lat. 0' 33' S., 

 long. 151" 34' W., about half-way between Hawaii and Tahiti, in 2425 

 fathoms, nine species of Keratosa, six of HexactincllidtB, and, in all, 

 twenty-nine species of Invertebrates and Fishes exclusive of Protozoa. At 

 the next station, 272, lat. 3' 48' S., long. 152' 56' W., in 2600 fathoms, 

 sixteen species of Invertebrates, and Fishes were collected. At Station 274, 

 lat. 7' 25' S., long. 152' 15' W., Taiiiti and the Marquesas about equidistant, 

 625 miles, Caroline Island 202, and Vostok Island 160 miles. At Station 

 276, lat. 13' 28' S., long. 149' 30' W., in 2350 fathoms, Tahiti distant 240 

 mile.s, only six species (10 specimens) of Invertebrates and Fishes are re- 

 corded from the trawl, while the hauls off Tahiti, though poor, contained 

 again a comparatively large number of specimens and species. 



On the line from Tahiti to Valparaiso the liauls at Station 280, 1940 

 fathoms, and at Station 281, 2385 fathoms, distant from Tahiti less than 

 200 miles south, again showed a very great diminution in the number of 

 specimens and species collected in the trawl. A similar condition exists 

 at Stations 285, lat. 32' 30' S., long. 137' 43' W., and 286, in depths of 2375 

 and 2335 fathoms, about 1300 miles southeast from Tahiti and nearly 

 600 miles south of the islands of the southeast extremity of the Paumotus. 

 The fauna at Station 289, kit. 39' 41' S., long. 131' 23' W., about 250 miles 

 southeast of Station 285, in 2550 fathoms, was equally poor. 



From Station 289 the "Challenger" ran a line nearly east towards Val- 

 paraiso, distant 2907 miles. At Station 291, lat. 39° 13' S., long. 118' 49' W., 

 in 2250 fathoms, only two species of Monaxonida were obtained. At 

 Station 293, lat. 39° 04' S., long. 105' 05' W., in 2025 fathoms, an Actina- 

 rian and fragments of siliceous sponges and Gorgonians and Polyzoa were 

 obtained attached to manganese nodules; Valparaiso distant 1661 miles. 

 One specimen of Holopsamma was obtained at Station 294, lat. 39° 22' S., 

 long. 98 46' W., in 2270 fathoms, Valparaiso distant 1368 miles. At 

 Station 295, lat. 38° 07' S., long. 94° 04' W., one fish (Cyema) was collected 

 in the trawl, which is also, like Gonostoma, probably a fish belonging to
