Universally distributed, generally abundant. The typical B. fusiformis of Williamson, 

 with an elongate test and a somewhat virguline aperture, though occurring at nearly 

 every Stn., is far less abundant than a short and somewhat inflated type with terminal 

 aperture. This short type appears to represent a passage-form into B. ooata. 



123. Bulimina ovata, d'Orbigny. 



Bulhnina ovata, d'Orbigny, 1810, FFV. p. 185, pi. xi. figs. 13, 14.

A single very large specimen at Stn. 17 and one or two small specimens at Stns. 19 

 and 20. The extraordinary rarity of this species in these gatherings is noticeable. 



121. Bulimina elegantissima, d'Orbigny.

This pretty little species, which appears to be more fixed in its characteristics thau 

 most of the Eulimintc, occurs at a good many Stns., but never very abundantly. The 

 best were at Stns. 4 and 11. It is subject to very little variation, except in the com- 

 parative length and breadth of the shell. At Stn. 4 one abnormally long and attenuated 

 individual was observed. 



125. Bulimina marginata, d'Orbigny. 



Bulimina niaryinata, d'Orbigny, 1826, TM(J. p. 209. No. 4, pi. xii. figs. 10-12.

24 Stations. 



Universally distributed and as abundant as B. eleyans, subject to the same lines of 

 variation — i. e., apart from typical specimens resembling d'Orbigny's figure, we find 

 marginate specimens which in the arrangement of their chandlers are closer to B. elegans, 

 d'Orbigny, and B. gibba, Eornasini. Abnormal specimens occur at Stns. 18, 20, and 21. 

 At Stns. 18 and 20 they consisted of pairs of individuals fused by their aboral extremities. 

 At Stn. 21 were several instances of individuals having double and treble apertures. 

 Such deformities may generally be found in any dredging where Buliminse preponderate.
