Rotner, in dealing with this species in his Monogder Moll., 

 Venus, Band I, sub-genus Cytherea, dated 1869, page 69, as 

 Cytherea (Caryatis) Kingii, Gray, pi. 26, fig. 1, gives C. modesta 

 of Philippi (not Sowerby) in Abbild. I., p. 198, pi. 3, fig. 3, as a 

 synonem, and Dione Philipjn, Desh., as another synonem ; but 

 Deshayes makes the Cytherea Modesta of Philippi in Abbild. 

 Conch., p. 20, No. 3, pi. 3, fig. 3, 1845 (not Sowerby) as a 

 synonem of Dioiie Philippi, Desh. He moreover makes Cytherea 

 Kingii (ex parte) of Sowb. in Thes. Conch., p. 638, another syno- 

 nem. He makes C. Bilunulata, as labelled in British Museum, 

 quoted by Sowei'by, as a var. of Kingii, a doubtful synonym. 



Reeve in his Monograph of the genus Dione in the Concho- 

 logia Iconica, Vol. xiv., pi. 9., fig. 36 a., b., dated on plate 9, 

 October, 1863, has to my mind figured C. Lamarckii, Gray, as 

 fig. 366. His figure 36a is certainly not Kingii, Gray, it is 

 Cytherea Loeta, Linne., from Philippine Islands. This is Reeve's 

 description of the species : — "Shell ovate, thin, rather compressed, 

 fulvous white, variously stained and rayed with red ; most 

 concentrically irregularly striated ; anterior side rather short, 

 rounded." 



What is supposed to be a var. or synonym of this species, under 

 the name of Cytherea Modesta of Philippi is described thus in 

 Abbildungen Conchylien by Dr. R. A. Philippi, dated 184.5, 

 p. 198 of Vol. u., sp. 3, pi. 3, fig. 3, of Cytherea :—" Shell 

 ovately oblong, somewhat compressed, thin ; transversly very 

 lightly striated ; whitish, ornamented with fulvous rays or 

 yellowish unicolored rays ; area wanting ; lunula lanceolate 

 scarcely distinct." The figure is a good one with rather pale- 

 coloured chestnut narrow rays, as it is often obtained in Bass's 

 Straits specimens. 



The shell with which this species has been confused, mixed up 

 with, or considered synonymous with, is Cytherea Lamarckii, 

 Gray. It was described by Gray in the " Analyst," a monthly 

 periodical of science, published in octavo form in London. Ten 

 volumes of this Journal were issued between 1834 and 1840, 

 when it either ceased or was merged into some other Journal. 

 The description is in Vol. vili., which was issued in 1838, on 

 p. 306, but not figured. I have never seen this Journal, and 

 cannot hear of a copy of it in New South Wales, otherwise I 

 would give his definition of the species. C. Lamarckii is recorded 

 by Hanley in his Illustrated and Descriptive Catalogue of Recent 

 Bivalve Shells, the plates of which form a third edition of Woods' 

 Index Testaeeologicus. It is described on page 103 of the letter- 

 press in Part I., issued in 1843. It was recorded also in the 

 Catlow Catalogue, sp. 58, on page 39, but so far still unfigured. 

 This work was published in octavo form in London, and is dated 

 1845 ; it is a joint work compiled by Miss Agnes Catlow and
