The name Chlamys (Chlamys) humilis Sowerby, 1904, was resurrected by Kilburn & Rippey (1982: 216) for a species that was relegated to the synonymy of Chlamys (Chlamys) tincta (Reeve, 1853) by Barnard (1964: 424-426). This conclusion was based on a series of newly collected material from Cape St. Blaize. The present author has studied the types of C. humilis and agrees with this conclusion. He has also checked the types of C. tincta and some of its synonyms. The type material of C. humilis consists of two valves from “Great Fish Point, N.W., 9 miles, depth 51 fathoms; bottom, sand and shells” (BMNH 1904.12.23.163)¹ and one complete pair from “Cape St. Blaize, N. by E., 1/4E., 65 miles, depth 90 fathoms” (SAM 14858). The type specimens are syntypes. The two valves from the BMNH, on which the description by Sowerby (1904: 3) is mainly based, without any doubt belong to C. tincta. The pair from the SAM, which is the specimen figured by Sowerby (1904: pl. IV fig. 3), represents a separate species. The specimen from the SAM is herewith designated lectotype of Chlamys (Chlamys) humilis Sowerby, 1904. The valves from the BMNH consequently become paralectotypes of the same species, but the paired shells belong to C. tincta.
