south, and perhaps the abundance of jellies was connected with this. 



At 8:30 p. m. ran out otter trawl with half- meter net attached and 

 secured about the same forms as in metre nets at 8 and 9 o'clock. 

 A hundred or more Myctophids, almost all two inches or more in 

 length, and the majority Lampanyctus macropterum, a form new to 

 the Pacific, seven giant Leptocephal^is, and two wonderful Scopeloids, 

 with large teeth, long barbels and the dark brown skin covered with 

 small light-organs. 



Noon position: Lat. 6° 33' N: Long. 82° 43' W. 



May 13th. Station 66. Successful hauls with a Petersen at 600, 

 and three metre nets at 600, 500, and 300 fathoms. From the Peter- 

 sen we obtained: 



1 Stomias colubrinus (145 mm.), 4 Melamphaes mizolepis, 1 Melam- 

 phaes nigrescens, and 2 Lampanyctus macropterum. 



The metre net at the same depth yielded Lampanyctus oculeum, and 

 the 300 fathom net brought in several Vinciguerria lucetia. 



Worked hard on yesterday's material, and in evening surface haul 

 (8 p. m.) got almost no fish, only 2 Myctophum coccoi, I large Lep- 

 tocophalus and 2 Lampanyctus macropterum. 



Noon position: Lat. 6° 25' N: Long. 85° 06' W. 



May 14th. The following is a list of fish caught in a typical Pacific 

 haul, the list belonging properly to future technical papers. Sound- 

 ings and temperatures at daylight. Half-hour haul at 5 a. m. yielded 

 large numbers of Halobates and pale pink plankton. The fish were: 



4 Myctophum coccoi. 



1 halfbeak. 



2 young Coryphaena. 



1 small Coryphaena-like, dark-finned fish. 

 1 yellow-banded flyingfish. 

 1 oval four-banded fish. 



From 9 to 11 a. m. towed a Petersen and four metre nets, with 

 following results: 



Metre net at 300 fathoms. 



Numerous Vinciguerria and small white Cyclothones. These resem- 

 ble each other and form a semi-transparent white zone of fish. 

 Metre net at 400 fathoms. 



400 white Cyclothones. 



200 black Cyclothones. 



Numerous small Myctophum laternatum. 



1 very elongate long-barbeled fish. 



Large white transparent Octopus, with two circles of light-or- 

 gans around eyes. 

 Metre net at 500 fathoms. 



Net torn, contained only one white Cyclothone. 

 Metre net at 600 fathoms. 



1 seven-inch Chauliodus sloanei.
