RM2CNHTRM–. California fish and game . OF NORTHERN CALIFORNIA.* By Will F. Thompson. In northern California there are found three species of abalone:namely, Haliotis rufescens, Swainson, the red; H. cracherodii, Leach, theblack; and H. wallalcnsis, Stearns, the northern green abalone. Earnestsearch has failed to reveal the abalone of British Columbia and Alaska,H. gigantea, Chemnitz. But one of these, the first named, is found innumbers rendering it of importance as food. It is exceedingly difficultto gauge the absolute abundance of this red abalone in any place withoutthe aid of divers apparatus. For t

CALIFORNIA FISH AND GAME. 47 Abalones dwell solely along the outer coasts, but there they dwellwherever they are afforded a foothold on or beneath rocks on a coastfree from loose sand and mud. The red abalone is found below extremelow tide line and occasionally a little above, the black is at a higher leveland rarely below low tide line, Avhile the northern green abalone is foundonly at about lov,^ tide level as far as known. All species agree, however,

Changes in the biochemical composition during the com- plete development of Haliotis rufescens, from the unfertilized oocyte (day 0) to a larva fully competent to settle. Larvae in Culture 1 took 7 days to reach competence; those in Culture 5 took 5 days. For each sample the dry' organic weight is represented by the sum of the weights of protein, total lipid, and the uncharacterized fraction (remainder). The cross-hatched portions o

Induction of attachment of larval Haliotis rufescens by excess potassium, when present in addition to the chemical inducer GABA. The concentration of GABA was 4 X 107 M. The percentage of larvae attached was scored at 22 h (O), 48 h (A), and 71 h (D) of continuous exposure, with other details as in the legend for Figure 1. For values obtained in the absence of GABA, see Figure 2. or the response of P. sibogae larvae to coral extract (Table I A). The effect of TEA
