bourhoocl, read before the Roy. Soc. of N. S. Wales, 3rd June, 

 1889, and published in their Journal and Proceedings as Acmcea 

 cinnamomea, p. 272. 



The specimens in the Australian Museum are still named 

 incorrectly Emarginula stellata ; to prevent future mistakes I 

 think it worth while giving the correct name of the species in our 

 Journal. The fact is that the species referred to as stellata is 

 neither an Emarginula nor a Scutellina ; it is a Subemarginula, 

 and was described by A. Adams in 1851 in Proc. Zool. Soc. p. 87, 

 as Clj/ioidina stellata; the latter is figured in Sowerby's Thesaurus, 

 p. 219, fig. 103. 



SctitelUna cinnamomea will be found fully described and well 

 figured in Tryon and Pilsbry's Manual of Conchology, Vol. xii. 

 p. 128, pi. XLVi. figs. 8, 9, 10, 11. 



Chiton piceus, Reeve. 



This species is recorded in Angas's List of the Marine Mollusca 

 found in Port Jackson and on the adjacent Coasts, in P.Z.S. for 

 1867, p. 223, No. 241, as Ch. piceus oi Gmel., with a reference to 

 its description in Syst. Naturae, p. 3204. 



It is a very common species, as Angas remarks, " freely distri- 

 buted on most parts of the coast, dwelling in cavities on exposed 

 parts of the rocks," generally found about high-water mark, — at 

 least this form is; I think, from a minute examination of the 

 spines on the mantle and of the disarticulated valves, that this 

 is Acanthopleura sjnniger of Sowerby. Sowerby described this 

 species in 1840 in Mag. Nat. Hist. p. 278, Suppl. pi. xvi. fig. 2. 

 He figured it also in Conch. lUust. fig. 69, as Ch. spiJiiger. 



A Chiton was described by Linmeus as Chiton aculeatus in 

 Syst. Nat. x. p. 667, founded on Rumphius' Amboinische Rariteit- 

 kamer, pi. x. fig, 4, which was supposed to be this species, but the 

 original description was so vague that Hanley suggested that the 

 species should be dropped. 



Chiton piceus of Reeve was not described till 1847 (in Conch. 

 Icon. Monograph of Chitons, pi. xiii. fig. 70).
