In discussing the second and third aims of this paper (see p. 20), the dis- tributions of Hygophum benoiti (characteristic of the subtropical grouping) and Electrona risso, Benthosema glaciate, and Lampanyctus crocodilus (all character- istic of the Temperate Region) are examined. Backus et al. (1977) are of the opinion that Electrona risso (Fig. 18) is an Eastern Pattern species, which would seem to support its inclusion with the other temperate species in the context of the 1979-transects. Hulley (1981), on the other hand, suggests a relationship with the 10 °C and 15 °C isotherms at 200 m and the 50 gCnr2y_1 isoline. Except for the single larval specimen taken in a neuston tow at about 28°N 51°W, for which there is some doubt about the identification ( John, pers. comm.), the latter criteria are satisfied by the.
