The temperature was moderate at the surface and fell ,?° 

 in the 100 meters, the salinity and hydrogen-ion concentra- 

 tion remaining constant. Fourteen species were present at the 

 surface, 22 in the 50-meter tow, and 35 in the 100-meter tow. 

 Tvvent>'-fi\e species (55 per cent) were each confined to a 

 single tow and 6 were found in all three tows. Corycaeus and 



Oilhona presented many species, but comparatively few 

 specimens, and this paucity in numbers was shared by nearly 

 all the other genera, since only two of them were recorded as 

 abundant. As at the two preceding stations, Microsetella w^as 

 found onl\- in the 100-meter tow, although it is usually a 

 surface form.
