![M. chilopora (Reuss) l, but the general form of the zooecia and the structure of the mucro are quite distinct in the two species. Mr. A. Bell’s collection of Fareham Bryozoa having recently passed into the posses- sion of the British Museum, I am able to identify with this species the specimen referred to by Vine as Porella concinna. Mr. Waters, in his ‘ Revision of the North Italian Bryozoa,’ does not quote Mucro- nella from the Eocene deposits of that country. The genus occurs in the Austrian Leithakalk (Helvetian), as at least two species, M. serrulata (Reuss) 2 and M. tenera (Reuss) 3, seem referable to it. Mr. Waters [No. n, pp. 14, 15] has shown that under the name “ mucro” several distinct structures have been confused together, and he has proposed the dismemberment of Mucronella and the incorporation of most of its species in Smittia. The generic value of variations in the secondary orifice and its peristomial tube certainly appears very doubtful, but there does seem sufficient difference between this group of species of Mucronella and normal Smittice to justify the limitation and retention of Mr. Hincks’s too comprehensive genus. Genus Smittia, Hincks, 1880. Diagnosis. Hincks, No. i, p. 340. Species 1. Smittia tubularis 4, n. sp. Diagnosis. Zoarium erect; narrow cylindrical or shoot-like branches; branching dichotomous. Zooecia arranged alternately. Shape pyriform ; ovate or elongate-ovate. Front wall tumid; surface granular. Secondary orifice orbicular or a distinct spout-like depression often shown on lower margin. Peristome thin. A row of large areolse occurs around the margin. Ocecia small, flattened, the lower side covered by the upper margin of the secondary orifice. Avicularia large, lateral, on a prominent tubercle obliquely below the orifice. Distribution.
