Genus CYMBALOPORA Hagenow, 1850.

D'Orbigny described this species from the West Indies, noting that 

 it occurs plentifully adhering to Fucus and Viva Lactuca. The form 

 described as R. squammosa has a much higher spire, but seems, from 

 the figures at least, to be very close, if not identical with, C. poeyi. 

 The low form is the one that is abundant at Jamaica. 



Although not observed attached to algae at Montego Bay, the speci- 

 mens were noted as occurring in much greater abundance in depths 

 of 1 fathom (2 meters) or less, than in 3-10 fathoms (5-1S meters). 

 At the lesser depths it was very abundant. Specimens were collected 

 at stations 1, 2, 4, and 6 at Montego Bay and at Runaway Bay. 



This is one of the species which is widely distributed either in its 

 typical form or varieties in the tropical Pacific, as well as the West 

 Indian region. 



Genus TRETOMPHALUS Moebius, 1880. 



TRETOMPHALUS BULLOIDES (d'Orbigny). 



Plate 13, fig. 13. 



Rosalina bulloides d'Orbigny, Foram. Cuba, 1839, p. 98, pi. 3, figs. 2, 3. 

 Cymbalopora bulloides Carpenter, Parker, and Jones, Introd. Foram., 1862, 



p. 216. 

 Tretomphalus bulloides Moebius, Beitr. Meeresfauna Insel Mauritius, 1880, 



p. 98, pi. 10, figs. 6-9. 



This is rare in 6 fathoms (11 meters) at Montego Bay. It is a 

 pelagic species at least in adult condition, and has a wide range in 

 comparatively shallow water in the Pacific and Indian Oceans, as 

 well as south to Australia. 



Genus SIPHONINA Reuss, 1849. 



SIPHONINA RETICULATA (Czjzek). 



Rotalina reticulata Czjzek, Haidinger's Nat. Abb., vol. 2, 1S48, p. 145, pi. 13, 



figs. 7-9. 

 Truncatulina reticulata Bronn, Letbaea Geognostica, ed. 3, vol. 3, 1853-1856, 

 p. 227, pi. 35 (?), figs. 23a-c. 

 There seems to be no figure or description in d'Orbigny's Cuban 

 Monograph which at all apply to this species. Specimens were found 

 at Montego Bay at stations 1 and 5, at both of which it was rare. 



The numerous forms or species referred to this species are evidently 

 a complex which needs revision. There are numerous species in this 

 general region, both living, and in the Tertiary, a close study of which 

 should give some idea as to the relation of the different forms.
