SEELEY, H. 1861. Notes on Cambridge paleontology. I. Some new Upper Greensand bivalves. The Annals and Magazine of Natural History [Third Series], 7: 116-124, pls. 5, 6. [p. 119]
1861 Hinnites pectinatus Seeley, 1861
«A very marked variety occurs which has good claims to be considered a distinct species. It is distinguished by having all the ribs much closer and higher, and those of the convex side nearly as wide as the intervening spaces; it also commonly has a striation in each interspace, and as many as five wide folds on each rib. On the flat valve the folds on the ribs are very obscure; the interspaces commonly have a single strong striation, and appear to have been finely striated transversely. I have provisionally marked it Hinnites pectinatus.»
