Fig. 84. — Genus Puellina Jullien, 1886. 
A-E. Puellina gattyae Busk, 1S52. A. Zooecia and ovicells, X 26. (After Hincks, 1880.) 
B. Zooecia from the basal surface. The dietellae ( psch ) surround the zooecia and their ovicells, 
X 40. (After Levinsen, 1909.) C. Opercular valve, X 85. (After Waters, 1878.) D. Anterior 
portion of a zooecium of the ordinary form. E. Variety, with interesting duplicated lateral 
lacunae. (Figs. D, E. After Norman, 1903.) dla, duplicated lateral lacuna; la, lacuna; ph, 
papillae holes. 
F. Puellina innominata Couch, 1844. Sketch showing terminology. Three costules of a zooe- 
cium showing the lateral papillae and a small opening outside the arch of the costule, into the 
body of the polyzoon, which a papilla has occupied. (After Norman, 1903.) 
G-J. Puellina radiata Moll, 1803. G. Zooecia with avicularia, X 25. H. Avicularian man- 
dibles, X 50. (G, H. After Hincks, 1880.) I. Avicularian mandible, X 85. (After Waters, 18S5.) 
J. Primary zooecium ( pz ) and three younger zooecia. The frontal flustrine membrane (pz) is 
overarched by a proximal scutum-like spine (sc) while the ten other spines bear minute horizon- 
tal calcareous lobes which project from the inner sides. The oral spines of the zooecium bear 
similar lobes. In all except the primary zooecium (ancestrula) the series of oral spines is con- 
tinued by the pair of elongated membraneous spines (sp) (papillae of Norman) on either side 
of the median pore (nip) and further by the small papillae (sp') (papillae holes of Norman) 
which correspond with the marginal spines of the primary zooecium. The series of pores are in 
the same radii as those modified spines. The pore chambers (dietellae) are not indicated. 
(After Harmer, 1902.)
