is apparent, and some wliere it is altogether fiery crimson. 

 In the females it is apparently the same ; for I have some 

 with blackish rumps, while others show a tinge of crimson, 

 which colour, in the adult birds, extends all over the rump.

Without professing quite to understand the details of Sol- 

 dani's figure, we have little hesitation in regarding this as a 

 variety of Cornnspira foltacea. Figs. A, B, C, D, G, & H, 

 pi. 47, are also either Cornuspirce or SpirillincB. They are of 

 minute size (except fig. ZT), and hence were greatly misunder- 

 stood with the imperfect microscopies then in use. Larger 

 specimens of Foraminifera were drawn by Soldani's artists 

 much more true to nature, and often remarkably so.

Whatever decision may be arrived at with respect to the 

 last-named species must obtain also with this, which has the 

 same characters, save that slight constrictions at the periphery 

 appear to indicate in this form the partial subdivision of one 

 or more tm'ns of the spire into chambers. In both cases 

 the earlier turns of the spire are not septated. With some 

 hesitation, we are disposed to consider this also a subvarietal 

 modification of Gornuspira. Possibly the septations have been 

 deepened by the artist.

Very doubtful ; either another asj)ect of Cornuspira or, 

 perhaps, a granular Spii'illina, in which the exostoses have
