In November 1954 the Rev. Father CHR. VAN DEN HOF collected a number of about 300 living specimens of a Subulina-species in the environments of Yanonge in the Belgian Congo, and kindly presented the first named author with them. The shells are now in the collection VENMANS and registered under No. 6793. Mr. G. RANSON, curator of the malacological department of the Natural History Museum at Paris, kindly compared them with the Subulina-material in his Museum, and came to the conclusion, that they belonged to the species Subulina kassaiana Rochebrune & Germain.
