41 38 Figs. 34-41. Acanthochitona astrigera (Reeve, 1847). Fig. 34. Whole specimen, 20.2 mm; Eight Mile Rock, Grand Bahama; FSBC I 32527. Fig. 35. Valve i ex 15.0 mm specimen; same lot. Fig. 36. Valve iv, same specimen. Fig. 37. Valve v ex 18.1 mm specimen; same lot. Fig. 38. Valve viii ex 12.2 mm specimen, same lot. Fig. 39. Valve viii, same specimen as 35. Fig. 40. Valve viii, same specimen as 37. Fig. 41. Tegmental pustules, valve iv, same specimen as 38 (field width = 280 ^m). A. astrigera, but he cited Smith as authority in designating astrigera a variety of A. spiculosa despite the fact that Smith chose to use astrigera, not spiculosa, for his material. Pilsbry cited no material of A. spiculosa s.s. Thereafter, A. astrigera was reported by many authors under the name A. spiculosa, as were many specimens of A. pygmaea and other taxa. Kaas (1972) reported as A. spiculosa specimens of A. astrigera from Grand Bahama Island, but he also reported some specimens of A. pygmaea as A. spiculosa (see remarks for that species). Watters (1981) correctly noted that A. astrigera and A. spiculosa were distinct, but he included an undescribed species within his concept of A. astrigera, and he supported Dall's misconception that A. spiculosa represented the species otherwise known as A. pygmaea (Pilsbry, 1893). Fer- reira (1985) followed Watters' concepts of both A. astrigera and A. spiculosa. Thus, published records of Acanthochitona spiculosa and A. astrigera, its supposed synonym, actually include A. astrigera, A. pygmaea, and, according to material I have examined, some specimens of A. andersoni Watters, 1981, and a new species described hereafter. Specimens illustrated as A. astrigera by Watters (1981) from La Parguera, Puerto Rico, and Water Id., Virgin Islands, are the new species. Likewise, Ferreira's (1985) record of A. astrigera from Belize was based upon an IRCZM specimen of the new species. The literature can be corrected only when previously reported specimens, including E. A. Smith's Fernando Noronha record, have been re-examined. Dall (1889a) listed Acanthochitona astrigera from Dry Tortugas and the Florida Keys, but I have seen no specimens from Florida. At Grand Bahama Island, A. astrigera lives prin- cipally among brown algae in the intertidal zone of high wave
