58 BULLETIN: MUSEUM OF COMPARATIVE ZOOLOGY. 
In his synopsis of the British Recent Foraminifera, 1887, Journ. R. 
Microsc. Soc., 1887, (2.), VII. p. 911, Brady has used the name of 
elongata, but that epithet was long ago bestowed by d’Orbigny on a 
winged and broader form of crepidula. Brady considers this form also 
to be nearly identical with C. obtusata of Reuss, but that form has its 
allies amongst a set of Cristellariz peculiar to earlier tertiary horizons, 
distinguished by their tumid segments. 
Sometimes it has the sutures strongly limbated, a fine specimen of 
that feature having been met with amongst ordinary samples in the 
Caribbean Sea. Montagu has also represented his subarcuatula with 
limbated sutures. The specimens met with in the Pacific are very 
slender, and approach in appearance Vaginulina levigata RoEM. 
Pacific. 885-1201 fathoms. 
Caribbean Sea. 347-420 fathoms.

C. italica Br., Chall. Rep., LX. p. 544, Pl. LX VIII. Figs. 17, 18, 20-23. 
This is an easily distinguished form, when in a certain state of development, 
but sometimes forms are met with which can hardly be distinguished from thick 
Marginuline or from some varieties of C. crepidula. Sometimes it develops 
itself in a prolonged row of segments attaining a length of 8 mm. 
Caribbean Sea. 169-658 fathoms; not scarce.

Marginulina-formed, elongated shape, owing to the later segments’ arrange-
