Nomenclature of the Foraminifera. 341 



Menardii, D'Orb., are through numerous and more or less ob- 

 long varieties, as yet undescribed, from the very deep soundings 

 in the tropical parts of the Atlantic Ocean. 



18. Vol. i. p. 126. 32 e genre. Eponides repandus. After Fich- 

 tel and Moll. It is the Rotalia repanda. 



19. Vol. i. p. 130. 33 e genre. Storilus radiatus. From the 

 Persian Gulf and Leghorn. This is a Rotalian form, flat on one 

 side and strongly umbonate on the other. It is difficult to con- 

 jecture its identity with any known form, though it may be 

 meant to represent some large variety of Rotalia Beccarii, which 

 is extremely variable in its growth in different seas. 



20. Vol. i. p. 134. 34 e genre. Florilus stellatus. A bad draw- 

 ing after Fichtel and Moll's figures of Nonionina asterizans. 



21. Vol. i. p. 138. 35 e genre. Polyxenes cribratus. After 

 Fichtel and Moll's figure of Planorbulina farcta, 



22. Vol. i. p. 142. 36 e genre. iEolides squammatus. The figure 

 in Soldani's ' Testaceographia ' (pi. 167. fig. v v) which De 

 Montfort has here copied, with fanciful modifications, is one of 

 Soldani's " Reteporse muscipulse minima?." There is no doubt 

 that Soldani's specimen was a young and somewhat excentric 

 Orbitolites complanatus. Four or five other dwarfish and some- 

 what worn specimens are figured by Soldani in pis. 167 & 168, 

 with a want of his usual clearness of delineation, his notion of 

 the relations of these little Orbitolites (always small in the 

 Mediterranean, especially at Leghorn) not having been very 

 definite. 



23. Vol. i. p. 146. 37 e genre. Tinoporus baculatus. Modified 

 from the figure of Calcarina Spengleri, var. a, F. & M. ; or, rather, 

 this is apparently a curious hybrid picture, consisting of a three- 

 spined Orbitolina*, according to its surface-ornament and its 

 vertical section, but outlined after a three- spined Calcarina 

 Spengleri (such as fig. e. pi. 15, in Fichtel and MolPs ' Test. 

 Microsc/). The indication of an aperture (the broken newest 

 chamber in Calcarina) is also after Fichtel and MolFs figure. 

 The sectional aspects in Montfort's woodcut appear to have been 

 taken, the vertical (Orbitoline) from nature, the horizontal (Cal- 

 carine) from Fichtel and MolFs fig. k, with the sectional feature 

 of the spine (also Calcarine) added from some other source. 

 Some stellate variety of Orbitolina sphcerulata may perhaps claim 

 the name of O. baculata, Montf. ; but Montfort's indefiniteness 

 may well lead us to drop the name altogether. 



24. Vol. i. p. 150. 38 e genre. Siderolites calcitrapes (Sidero- 

 lites calcitrapo'ides, De la Marck. Syst. An. s. Vert. p. 376). 

 Maestricht. This is the Rotalia (Calcarina) Spengleri, Gmelin
