 by Mr. Parker and his colleagues in Ann. Nat. Hist. Oct. 1871, 

 p. 238, pi. 8. figs. 1, 2. Figs. 20-20 are interesting specimens of 

 Ixuiena ijlohosa and some attenuate varieties, with (fig. 22) a prickly 

 variety. Figs. 27-21), however, though Lageniform, are most j)ro-

 in growth. PI. 2<) (^thirty figures) illustrates various conditions of 

 Noilosaria raphanux. A few such (figs. 1-4) occur also in pi. 27, which 

 is mainly occupied by variations of N. radicnla, passing into the 

 variable Dentalina co7n)i)unis (figs. 5-34). The same maj' be said of 

 pi. 28. Figs. 1-17 of pi. 25) belong to the same categorj' ; but fig. 18 

 (" N. a(fi/hitinfnis''') is most likely a Nodosariform Litunht. Figs. 

 19-30 are arranged in three species of Webbina ; but figs, 19 & 30, 

 though doubtful, must go with figs. 20-23, 25 & 20, as Niibeadance ; 

 whilst figs. 24, 27-29 are Webhin<i>. Fig. 24 is a curious, heaped, 

 or accr\-uline Webbina. Figs. 25 & 26 may be regarded as typical 

 Nubecidaritv. 



Lastly, we must remark that both the Liassic and the Oolitic 

 Foraminifera figured in these Memoirs may, with advantage to the 

 student, be compared "with the English specimens from the Upper 

 Keuper (Rha?tic ?) Clay, figured hy Jones and Parker in the Geol. 

 Soc. Journ. vol. xvi. ISOO, \t\s. 19 tk 20, and Avith those from the 

 Lias figured by H. B. Brady in the Proc. Somerset. Archa^ol. Nat. 

 Hist. Soc. xiii. 1867, pis. 1-3. A \cvy large proportion of M. Ter- 

 quem's species and varieties will be there found, with the old names 

 applied to them. Similar forms occur in the Upper Triassic strata 

 of Saint Cassian and Ilaibl, as figured by Dr. C. Giimbel in the 

 ' Jahrbuch k. k. geol. lleichsanstalt,' xix. 1869 ; and lleuss, Schwager, 

 and others have published Jurassic Foraminifera of the same types.

 Note on the Ptilornis Alberti. By G. E.. Gray. 



Mr. Elliot, in the ' Proceedings of the Zoological Society,' just 

 published, has made some remarks on the adoption of a MS. name 

 that I gave some years ago to the Northern-Australian Ptdomis, 

 when observing the differences which appeared to exist between it 

 and that of New Guinea. Mr. EUiot is right in remarking that I 

 had never published, but he is wrong in stating that I never " wrote " 

 any account of it. The reasons of the non-publication were : — 

 1. That Mr. Gould had already fully described and beautifully
