The acci- dental drop in temperature in 1958 was indicated in the scales by a pro- nounced annulus. The shape of most key scales was regular but heavy absorption at the dorsal and ventral edges (Fig. 4) occurred in some col- lected toward the front or rear end of the body during the last two years. The first key scales were collected from the series above the lateral line, dorsal to the origin of the pelvic fin. True annuli were readily dist

The first key scales were collected from the series above the lateral line, dorsal to the origin of the pelvic fin. True annuli were readily distinguished, but between them there were several confusing false annuli. I was, however, unable to relate scale growth to body growth, and values of body size back- calculated from scales for previous growth seasons do not make sense. Interception of annuli may be initiated by the intervals of life history and "the planetary yearly system" (Balon. 1971b. p. 99), but temperature or other environmental factors may strengthen the annulus interception (Seger- strale. 1932). The above data are recorded as a stimulus to interest, and in order to complete the description of the artificially dwarfed carp. The results of this 15
