EDMONDIA ACCIP1ENS. 333 



Sowerby described JInio TJrei as having its " posterior extremity rather 

 pointed," but this was not correct, for he did not recognise that he was 

 describing a specimen with an incomplete posterior end; similarly he does not 

 seem to have recognised that his type of U. parallelus was a fragment only, for 

 the measurements given are those of the broken shell. 



Mr. Etheridge described a shell [op. supra cit.) in the cabinet of Mr. J. Ward, 

 of Longton, as Sanguinolites granulosus, which was stated to have come from the 

 North Staffordshire Coal-field at Adderley Green, horizon uncertain. This shell is 

 identical with the specimens from Coalbrookdale, which also possess the minute 

 tubercles thought to be characteristic of his new specimen by Mr. Etheridge. In 

 this character E. accipiens agrees with E. Lyellii and E. sulcata. I am very 

 doubtful whether the shell in question was really obtained from North Stafford- 

 shire. Mr. Ward himself is very doubtful where he obtained the specimen, and 

 I have had several talks with him on the subject, and judging from the matrix 

 and condition of his specimen I am of opinion that it originally came from 

 Coalbrookdale, from which place he has a fine series of shells. Mr. Ward has 

 been such an accurate and careful collector that I feel sure that the find of a 

 marine shell in the Coal measures of Adderley Green would never have given rise 

 to an uncertainty of the horizon in his mind. In this specimen the ridge 

 described by Mr. Etheridge is due to crushing. I re-figure the specimen by the 

 kind permission of Mr. J. Ward, fig. 9, PI. XXXVII. 



Edmondia accipiens more closely resembles E. sulcata than any other species 

 of the genus, but is distinguished by the following characters : — The umbones are 

 more anterior and the shell more inequilateral ; the sulcations and rugas are not so 

 well marked, and tend to split up into lines and plicse of growth. The valves are 

 more transverse. There is also a somewhat close resemblance to Allorisma sulcata, 

 but the presence of escutcheon, lunule, and sinuate pallial sinus in the latter at 

 once seems to separate the two species.
