PEOBOSCrN^A. 
No. D'. 2026. It does not show the narrow, constricted mouth 
conspicuous in Tine’s figure (Quart. Journ. Geol. Soc. vol. xivi. 
pi. xix. fig. 6i). The type of Vine’s Proboscina Clementina cannot 
be found in his collection, and his figure is indefinite. 
The Jurassic representative of this species is P. jacqiwti, Haime,^ 
which has even longer zooecia, while the zoarium consists of 
flabellate tufts connected by a narrow stolon-like band.
