Margarita. Eye-like bodies at the base of the lateral filaments, indicated 
by Agassiz in 1849, are more exactly described and figured by R. Bergh in 
his monograph of Thidiana^ Nat. Foren. Vid. Meddel. 1867, p. 109, pi. d «• 
figs. 9-16 j they contain pigment-cells similar to those of the eye of the same 
animal, and may safely be named accessory eyes. Some details about the 
eye are added, p. 110, footnote, figs. 16, 17 (also in Ann. & Mag. Nat. Hist, 
ser. 4. ii. pi. 1. figs. 11-19). The species in which those bodies have been ob- 
served are M. grmlandica (Chemn.) and cinerea (Couth.), var. grandis=M. 
striata (Brod. & Sow.).

Semperia, g. n., Crosse, Journ. Conch, xv. p. 74. Shell with a slit in the
