We report five cases of anomalous right lobe of the liver diagnosed by computed tomography (CT). There were three men and two women, with an average age of 67 years. The right lobe was deformed and decreased in size in all patients. Hypertrophy of the left lobe was present in all patients.

Four patients with anomalous lobes of the liver were observed at MR imaging. In one patient the anterior segment of the right hepatic lobe was absent and in 3 patients the left hepatic lobe was anomalous. The hepatic vasculature supporting the information of the anomalous hepatic lobes was well observed in all patients.

This paper reports results of studies on the stored-product pests in confections conducted from August 1968 to November 1969 at six survey areas in Kochi and of experimental studies on Oryzaephilus mercator, which was first found to be resident in the district of Kochi in our present study, in comparison with O. surinamensis, a common species in Japan of the same genus, and a species of another genus, Plodia interpunctella, as well. Laboratory studies on the development of O. mercator and O. surinamensis depending on different ages of parents and temperatures were made. To sum up briefly, the important ones among these results are as follows. (1) Out of the total observed number of 1722 of confections, high infestation rates of pests, 2.67% (15 species) and 18.2% (26 species), were found in samples taken from confections for sale and those of return, respectively. And as the results of our survey for a year, we could recognize three common species of pests, O. surinamensis, O.
