Astartidju. 
Astarte (J. Sow., 1816). E. A. Smith gives a history of the genus, 
type scotica (Mat. & Rack.) = sulcata (Da Costa), and a critical list of the 
26 recent species, with full synonymy ; as to the question whether a 
crenulated or smooth margin of the valves may be a specific difference, 
the author comes to the result that crenulation is a mark of maturity in 
those species in which it is found; J., of Conch, iii. pp. 196-232. 
Jeffreys, tom. cit. pp. 233 & 234, contests the latter statement, and unites 
some forms into one species, which are distinguished by Smith. He also 
gives further critical notes on the European species, their synonymy and 
varieties; P. Z. S. 1881, pp. 711-713. A. acuticostata (Jeffr., 1877), and 
pusilla (Forbes), figured, pi. Ixi. figs. 9 & 10.

Woodia (Desh.) is not to be separated from Astarte ; Jeffreys, P. Z. S.

Crassatella (Lam.). H. C. Weinkauff begins a monograph of this genus 
in Kiister’s ‘ Conchy lien-Cabinet,’ Part 307, 16 pp. 6 plates, describing 
and figuring 20 known species. 
Crassatinay subg. n. of Crassatella^ for the smaller species with crenated 
margin of the valves ; id. 1. c. p. 1. 
Crassatella Icnockeriy sp. n.. Smith, 1. c. p. 491, Wydah, W. Africa. 
Gouldia (C. B. Ad.) E. A. Smith discusses the original description of 
this genus and enumerates the species referred to it by various authors. 
He comes to the conclusion, that most of them, including one of C. B. 
Adams’s original species, are small forms of the genus Crassatella, while 
G. cerina (C. B. Ad.), minima (Mont.), australis (Angas), and perhaps 
dilecta (Gould), belong to Circe. P. Z. S. 1881, pp. 489-491.

Cardita (Actinobolus) velutinus, sp. n., E. A. Smith, 1. c. p. 42, pi. v. 
fig. 8, West Coast of Patagonia. 
Carditella, g. n. Two cardinal teeth in the left valve, one in the right ; 
two lateral teeth in each valve ; external ligament small ; internal car- 
tilage minute, placed immediately beneath the apex of the valves. C. 
pallida, sp. n.. West Coast of Patagonia. Cardita tegulata and semen 
(Rv.) belong also to this genus. E. A. Smith, 1. c. pp. 43 & 44, pi. v. 
fig. 9. 
Carditopsis, g. n., exteriorly like Carditella, but no external ligament ; 
internal ligament considerably larger. For Cardita flahellum (Reeve).
