He suggests that the Brazilian material of Hastimima includes specimens of more than one species, if not of more than one genus.
Figure 88 Hastimima whitei White. Fragment of tergite. Natural size
Through the courtesy of the National Museum, we have been enabled to study the Brazilian specimens of Hastimima and have derived the following notes on these interesting fossils.
