Extract

The genus Collarothyris was erected by Modzalevskaya in 1970 (p. 155) with Meristella canaliculata Wenjukow, 1899, as type species. Wenjukow (1899) did not designate a type; however, on p. 143 he gave the measurements of two specimens, one of which was figured on Plate VII, figure 21, and designated holotype by Modzalevskaya (1970, p. 156). Unfortunately, this specimen is lost (see also Nikiforova, Modzalevskaya, and Bassett, 1985). Further checking of the collections of the Geological Museum of the Geological Institute of Science, Kiev (Ukrania), resulted in finding, among Wenjukow's (1899) original collection, one specimen (No. 367/165) labelled as Meristella canaliculata and whose measurements coincide with one of those given by Wenjukow (1899, p. 143). This specimen is here figured (Figure 1) and selected lectotype of Collarothyris canaliculata (Wenjukow).
