The branchiobdellidan slide collection of Professor Hideji Yamaguchi was rediscovered in 1995; however, all of the written records associated with it appear to have been lost. The slide collection has been examined, cataloged and deposited in the Invertebrate Collection of the Hokkaido University Museum, Sapporo, Japan (ICHAM). The collection was found to contain whole mounted specimens of all 17 species described by Prof. Yamaguchi, together with specimens of three other Oriental species described after his death. In addition, mounted specimens of some of these species were designated syntypes. Many sectioned and stained specimens were also cataloged, but those were not identified to species at this time.
