With a view to propagating the spiny lobster, Panulirus japonicus, several measures have been successfully put into force in the Wakayama Prefecture with coöperation of 29 fishery guilds there. But as to biology of the animal there remain many points to be made out. The biological minimum size of th species in the Wakayama Prefecture was determined by the present author to be 150-160cm in length, morphology of the pleopods being used as a critelion to distinguish adult from immature (Fig. 1). Tagged 163 specimens, 66-206cm long, were riberated and seven were recaptured about five months afterwards. Of these seven, five retained the tag (C. von Bonde's tag) in a perfect condition, and their rate of growth was determined as shown in Table 1.

Based on statistical data, I studied the causes of emigration as indicated in Figs. 1-8 with result as follows.
1. It can hardly be said that emigration from this coast is due solely to economic reasons through lack of natural productivity of the regions.
2. The causes of emigration from this coast differ from those from the Tazima District and from the Okinawa Islands.
3. The district which is preeminant in emigrants agrees with the one that has a high index-number for fishermen and with villages having a low index-number for agriculture and forestry.
4. People emigrate from villages that have a relatively high density of population.
According to these facts, non-intensive agriculture and decline in fishing lead to emigration from said coast. But the above causes are mostly of a negative character. The positive causes of emigration from this district will be discussed in the 2nd report.

On the cause of the emigration from Mzab in the “Island” of the desert, Jean Brunhes said “The Mozabites emigrate to the Tell to earn their living and they often grow rich there. They are emigrants who are not moved by great appetites or great desires (like the Anglo-Saxons), since they dream of returning to pass their old age. in their native country in a modest environment. They are not emigrants who are urged on by poverty in the strict sense of the word, for nothing is less poverty-sticker than the Mzab. They form a special class of emigrants who are only because their form of cultivation must be a rich man's cultivation, kept. up at great expense; the poverty that urges them toward the Tell is relative. They are not absolutely all emigrants and they do not all become emigrants; but, among the Mozabites, not to emigrate is to lose caste. In fact they are not outcasts, reduced to poverty, who go to seek their fortune in a more hospitable land”
The emigrants from the coasts of Kii-Peninsula are exactly as, just described. They went abroad, stimulated by seeing their neigh-bours who emigrated, returning in affluent circumstances, at the. same time exhorted to thoso by emigrants residing abroad and those who have returned home.
At first the emigrants in Siono-Misaki village (the south end of. Kii-Peninsula) went to Australia in the 16th year of Meiji (1883). as pearl-divers, since when the number emigrants from Siono-Misaki has increased considerable. To-day they. go abroad moved by the prevailing tendency in this village to emigrate. The cause that fostered emigration along the south coast of this peninsula is cause A. (Cause of emigration in my 2nd Report).
The foregoing facts were established as the result of my geopsychological survey on the south coast of this region.
