ON DEVELOPMENT, GROWTH AND DISTRIBUTION OF CARCINIDES MAENAS (L.) BY G. J. BROEKHUYSEN JR. . I INTRODUCTION The investigation dealt with in the present paper took place at the Zoological Station of the "Nederlandsche Dierkundige Vereeniging", Den Helder, where I was working from the latter half of 1933 until July 1936. The original aim of this investigation was to try and analyse and to explain the distribution of Carcinides maenas (L.), which, at least in the surroundings of Den Helder, appeared to be very characteristic. Everything seemed to point to the distribution of this animal being susceptible to comparatively small differ- ences in salinity. As full-grown crabs were less suitable animals for experimental 258 purposes, I experimented with their eggs. The rearing of the eggs in my opinion gave rise to interesting questions as regards the influence of temperature and salinity on their development; but the results did not explain the distribution of the full- grown animals. It appeared, though, that the distribution of the full-grown crabs during the period when their eggs develop, is favourable for this development. From the experiments, how- ever, it also appeared that it was not possible without any further data to find
