To examine the genetic diversity of Sicyopterus japonicus, 448 sites of the control region of the mitochondrial DNA were analyzed in 77 specimens from the four localities of Okinawa, Kochi, Wakayama, and Shizuoka in Japan. A total of 74 haplotypes were found in the individuals examined. The same haplotypes occurred in Okinawa and Kochi, Kochi and Wakayama, and two specimens in Wakayama. The average sequence in genetic characteristics within localities varied from 1.7% in Kochi, 1.6% in Wakayama to 1.4% in Okinawa. There was no significant difference in genetic characteristics among the three locations of Wakayama, Kochi, and Okinawa (10,000 times permutation test, P>0.05). The number of specimens from Shizuoka was too small to compare to the other three locations. The neighbor-joining tree of the mitochondrial DNA haplotypes for all specimens constructed from the Kimura's two-parameter distances suggested no evidence of genetic subdivision of S. japonicus. These results suggested that this species has a single panmictic population and their larvae probably have a high dispersal ability during their oceanic stage.

In Han China there were a number of civil service examination systems, one of which was called 賢良方正, Hsien-liang Fang-cheng (capable/good and sincere/uprignt) as a special recruitment system.In comparison to China's famous examination systems in later times, the Han systems have been studied so poorly and incompletely that by now they are still ambiguous and open to further question.The author in this article at-tempts to clarify mainly the special recruitment system, Hsien-liang Fang-cheng, by means of analyzing the criteria of official promotion.The bureaucracy of the Han times consisted of the 15 ranks of officials, covering from the fief-holders of 万石, wan-shih (10,000 bushels), to those of 百石, po-shih (100 bushels).The right to recommend competent can-didates for government offices was restricted to the supreme officials,ranking over the fief-holders of 比二千石, pi-erh-ch'ien-shih (equivalent to 2,000 bushels).These supreme officials were thus to promote the positions of lower officials, ranking 四百石, ssu-po-shih (400 bushels), and below, to those of higher officials, ranking 比六百石, pi-lu-po-shih (equivalent to 600 bushels), and above.It was, therefore, one of the aims and characteristics of the special recruitment system of the Han dynasties to raise and reform the lower-grade to the upper-grade personnels of government offices.Centering on this issue, he also discusses some indispensable problems associated with the officialdom in general and civil service examination systems of Han China
