GOLDSTEIN’S NOMINA NUDA OF CATENICELLIDAE 
Vittaticella castanea (Thomson). 
(PL XVIII, figs. 4, 5, 6, 7.) 
Catenicella castanea Thomson, 1858, p. 138, pi. xiii, fig. 3. 
Catenicella pyriformis Goldstein MS. 
Description . — Zooecium elongate-ovate in outline; greatest width, at middle 
level of zooecium, equals about half length of zooecium. The slightly concave 
proximal rim is situated in the middle third of the zooecium one-third of 
the distance from distal to proximal connecting-tube apertures. Height of 
aperture equals about half the distance from the proximal rim to the distal 
connecting-tube aperture. 
The triangular scapular compartments, at level of aperture, project 
laterally. The suprascapular compartments, small in extent, face obliquely 
laterally. The vittae, facing directly laterally, extend from slightly below 
level of proximal rim to distal connecting-tube aperture and communicate 
by a single row of nine to eleven septula. 
Axis of daughter zooecium inclined at about 35° to that of mother zooe- 
cium. The sub-circular ovicell, barely projecting above frontal of distal 
zooecium, has a crenate margin formed by ten to twelve depressions. 
Dimensions. — Zooecium: length, 0 57 mm., width, 0 27; aperture: 
diameter, 0 09; ovicell: height, 0 23. 
Observations. — The ovicell of this species is figured for the 
first time and proves to he of similar type to those of other 
species of Vittaticella. Thomson’s figure, which illustrates 
the appearance of the vittae as seen in transparent balsam 
preparations, suggests that the vittae are forwardly directed. 
Goldstein’s mounts show a similar appearance, but the vittae 
are clearly laterally-directed. 
This species is characterized by the length of the vittae and 
the projecting triangular scapular compartments. 
Vittaticella utriculus (Macgillivray). 
(PI. XVIII, figs. 12, 13.) 
Catenicella utriculus Macgillivray, 1884, p. 32, pi. lxxxix, fig. 5. 
Catenicella constricta Goldstein MS., Jelly, 1889, p. 35. 
Description . — Zooecium broadly ovate with triangular latero-distal projec- 
tions; greatest width, at upper level of scapular compartments, is less than 
length of zooecium. The slightly concave proximal rim is situated in the 
middle quarter of the zooecium one-fifth of the distance between distal and 
proximal connecting-tube apertures. Height of aperture equals about two- 
thirds of the distance from the proximal rim to the distal connecting-tube 
aperture. 
The triangular scapular compartments, at and above level of aperture, 
appear as promiment latero-distal processes. The suprascapular compart- 
ments, of small extent, are directed upward. The vittae, facing directly 
laterally, extend from slightly below level of proximal rim to distal connect- 
ing-tube aperture.
