of the Jurassic Bryozoa. 449 
in crowded areas the zocecia are pyriform*., ‘Transverse 
ribbing well marked. 
Peristomes slightly raised. 
Formula.—V/ 2 2 1*2. 
Distribution.—England: Cornbrash. Foreign: Bajocian, 
France; Bathonian, France and Germany. 
4. Proboscina Cunningtont, sp. n. 
Diagnosis.—Zoarium formed of loose flabelliform Stoma- 
topora-like tufts ; these may radiate from a centre, to form a 
circular zoarium. The branches begin uniserially, and may 
end in sheets containing twelve zocecia in width. 
Zoecia regularly cylindrical, front wall ornamented by a 
transverse wrinkling ; of medium length, broad. 
Feristomes with somewhat thickened rims slightly raised. 
Formula.—1 0 1 1-3. 
Distribution.—F uller’s Earth, Bruton (B. M. Cunnington 
Coll. no. 88742) ; Cornbragh, Corsham. 
A ffinities.—This species is well characterized by its loose 
Stomatopora-like zoarium. Some branches end in sheets, and 
these ally it to P. Rigauai (Sauv.). From this, however, it 
may be distinguished by the looseness of the zoarium. Its 
nearest ally is the recent P. major (Johnst.). (See Hincks, 
Brit. Mar. Polyz. p. 427, pl. lviii.) This, however, has a 
formula 2 0 2 1/4, and may be distinguished by the greater 
elevation of the peristomes and length of the zocecia. 
I have much pleasure in naming this species after William 
Cunnington, Esq., from whom the British Museum received 
the specimen taken as the type, and whose careful collecting 
has added so greatly to the knowledge of Jurassic paleontology.

Diagnosis——Zoarium forming dense circular tufts. The 
branches end in crowded tufts, which almost form Berenicea- 
like sheets. 
Zoecia cylindrical, short, thick ; front wall with a well- 
marked transverse ribbing. Surface punctulate. 
Peristomes raised into a thickened rim, but not reflexed. 
* Haime shows some pyriform and others elongated and cylindrical.
