What reading level is The Genera Corygnitis, Gemmaria, And Zanclea book?
To quickly assess the difficulty of the text, read a short excerpt:
— This genus was instituted by McCrady for a hydroid and medusa described by him from Charleston Harbor {Proc. EUiotl Soc. Nat. Hist. y l,p. 131), and named in honor of Professor Agassiz Corynitis agassvdi. Notwithstanding the fairly full description, especially of the medusa, a most remarkable confusion has crept into the literature in respect to the supposed relations of the species.
About the time that McCrady described his species Agassiz also described a new hydroid which he designated as ...Hahcharis spiralis.
(Con. Nat. Hist., 4, p. 239.) For some unaccountable reason he subsequently came to regard this species as identical with Mc- Crad/s Corynitis agassizii, and on page 340 (op. cit.), giv^priority to the latter name, ranking his Halocharis as a sjrnonym. That this was not a mere oversight or clerical error is evident in that on page 344 he recognizes McCrady's Zandea gemmosa as quite distinct from Halocharis, and this error is perpetuated by A. Agassiz in N. Am. Ac, p. 183. These errors have continued throughout the literature up to the present time, though, as will be shown, it has later come to be known definitely that the medusa which Mc- Crady described as Zandea gemmosa, or rather Gemmaria gemmosa, is liberated from a hjrdroid resembling Agassiz's Halocharis, indeed almost certainly identical with it.
