With regard to the last station, at which the larvae were found in each of the four nets from surface down to 500 m., it may be that the warm surface temperature, due to the proximity of the station to the convergence, produced the same favourable conditions for spawning and subsequent development as are more generally to be sought for in the warm deep layer below

The significance of the vertical distribution of the Metanauplii is considered in con- junction with that of later larval forms on p. 163. Later stages of development were present at all the stations where Metanauplii occurred, and it is interesting to compare their vertical distribution with that of the Metanauplii. In this comparison Sts. 639 and 648 have been regarded as exceptional and the distribution of the larvae taken there is not represented in Fig. 33. At the former station two Metanauplii were found, both in the surface net, and at the latter this stage was present from the surface down to 500 m., with greatest concentration between 100-
