486 CPtETACEOUS TELECYrODA 



posterior elongated tootli is meant a lateral tooth or not ; in any case it would 

 seem to replace it when it extends ' parallel with the dorsal margin.' Until this 

 point has been cleared up, and the relation of the shell to Cyjwina and Cicatrea 

 ascertained, it may be no advantage to replace Conrad's name by another one, 

 for the name Veleda had been used already in 1859 by Black wall for a species 

 of spiders. 

 On page 193, under 12. — Cijpr'ma migulata, Sow., note — 



Briart and Cornet (Foss. de Bracquegnies, p. 68, pi. viii, figs. 26-28, in 

 M6m. Cour. Acad., Belg., vol. xxxiv), give a figure of the hinge of both valves of 

 a species which they say is identical with Sowerby's C. angiUata, of which they 

 compared a specimen from Blackdown, and the hinge of which is badly represented 

 by Sowerby in his Min. Conch., pi. 65. Briart and Cornet's figm-es show the 

 species to be a Venilicardia, noticed (p. 190) as a sub-genus of Veniella. 



On page 194 add — 



50a. Cyprlna proccena, G limb el, (Ostbayerisch. Grenzgeb., 1868, p. 765), 

 from the Greensand at Neukelheim (Bavaria). The tumid form of the shell closely 

 resembles that of an Isoarca, hinge unknown. 



506. Cyprlna sub-rostrata, G limb el, (Correspondenz Blatt des Zool. Mineral. 

 Ver. zu Regcnsburg, vol. xxii, 1868, p. 65), has been proposed for the species des- 

 cribed by Geinitz as C. rostrata in Verst. von Kieslingswalde, p. 13, pi. ii, fig, 12). 



Under No. 69, Isocardia modiolus, Nilss., note — 



E,yckholt (Mel. paleont., Part 1st, 1852, p. 131,) considers this species to be a 

 Lithodomtis. 



69a. Jsoc«rc?/a ;S'o?o^rS^M, Briart and Cornet (Foss. de Bracquegnies, 1858, 

 p. 70, pi. vii, figs. 17-18). The general form of the shell resembles that of a 

 Ileiocardia, but also that of Goniosoma and some species of Opis. As the hinge 

 is unknown, a correct generic determination cannot be attained. 



On page 195 add — 



129«. Venilia elevata. Con., (Am. Journ. Conch., VI, p. 74, pi. 3, fig. 7), 

 has a form resembling that of Ileiocardia, but the hinge is unknown. 



1296. (Veleda J lintea, Con., is noticed as Cardiiim [Lcevicardimn] Unteunif 

 on p. 215, sub-No. 146. 

 On page 199, under Ctprina [cicatrea] coudialis, for Fig. 1, read Figs. 1-2.

On page 208 add after the third line from top — 



Criocardinm, Conrad, 1870, (Am. Journ. Conch., VI, p. 75). " Multiradiate ; 

 interstices spinose, ribs smooth ; anterior lateral tooth long and prominent." This 

 sub-genus, Conrad says, presents a singular deviation from the character of recent 

 spinose species, in having long, slender spines in the interstices between the ribs, 

 while the ribs are smooth. Tjq^e, C. ditmosiim, Conrad.
