104 EXPEDITION OF THE "ALBATROSS," ISOD-IOOO. 



30 22' N., long. 154' 50' W., Pliysilia appears, and tlie Kadiolarians vary 

 from twelve to seventeen species. At Station 257 there are not more than 

 four specie.s recorded for the surface, off Molokai there were not more 

 than five surfiice Kadiolarians obtained, and at Station 2G0, in the centre 

 of the Hawaiian group, there are recorded from the surface : Diatoms, Globi- 

 gerinse, many Kadiolarians, and other pelagic animals, such as Medusa), 

 Siphonophores, Sagittte, Annelid larvie, Copepods, Hyperids, Euphausia, 

 Pteropods, Tunicates, and Gasteropod larvte, though in the other groups 

 of pelagic animals there has been, as a general rule, a very marked uni- 

 formity in the surface hauls. 



The (open) tow-nets at Station 241, lat. 35' 41' N., long. 157' 42' E., 

 were sent to sixty fathoms, and at Station 246 they were sent into deep 

 water, and when brought up contained all the things found at the surface 

 and additional Kadiolarians different from tliose found at the surface. 



At Station 247, depth 2530 fathoms, lat. 35' 48' N., long. 179^ 57' W., 

 the (open) tow-nets were sent down to 1200 and 1500 fatlioms, and many 

 Kadiolarians " abundant in deposits, but only rareli/ taken in the surface 

 nets" (the italics are mine). On the surface at Station 249, lat. 37' 59' N., 

 long. 171° 48' W., the stomaclH of the Cirriped Zoe:i3 were filled with 

 Coccospheres, Coccoliths, Khabdospheres and Rhabdoliths, and their ex- 

 crements were composed of masses of these small Alg;^ and Diatoms. 

 The stomachs of Eupliausias contained the remains of Acauthometrie and 

 Diatoms. 



At Station 250, lat. 37' 49' N., long. 166' 47' W., the tow-nets attached 

 to the trawl "which must have towod for a time at a depth of from 300 

 to 600 fathom.s," contained Challengeridae, Tuscaroridaj, and the like, which 

 were not found in the tow-nets dragged within thirty fathoms of the 

 surface. 



At Station 251, lat. 37' 37' N., long. 163' 26' W., Velella was very abun- 

 dant again. At Station 254, lat. 35° 13' N., long. 154' 43' W., a tow-net 

 haul was made in 100 fathoms containing ChallengeridoB. Murray again say.s, 

 at Station 257, distant 402 miles from Oahu, lat, 27 o.Ji' N., a liaul of the 

 tow-net from 500 fathoms "brought up Globigerina, Orbulina, Pulviiiulina, 

 Phaeodaria, and other Kadiolaria wd usually observed at the surface" (the italics
