FOLYSTOMELLA cf. STRIATO-PUNCTATA (Fichtel and Moll). 



This is a much overworked species, which undoubtedly includes 

 several distinct species or varieties. 



The Jamaican specimens apparently represent two distinct forms, 

 of which one is close to P. poeyana d'Orbigny of the Cuban Mono- 

 graph. Until a revision of the genus can be attempted with abun- 

 dant specimens the material had best be referred here. Specimens 

 were from Montego Bay, stations 1, 4, and 6. 



Genus AMPHISTEGINA d'Orbigny, 1826. 



AMPHISTEGINA GIBBOSA d'Orbigny. 



Amphistegina gibbosa d'Orbigny, Foram. Cuba, 1839, p. 120, pi. 8, figs. 1-3. 



The Jamaican specimens, which are very numerous at nearly all the 

 stations, but especially so from 6-10 fathoms (11-18 meters), are all 

 of the form described by d'Orbigny in the Cuban Monograph. 

 Whether this is really different from A. lessonii d'Orbigny may be 

 questioned, but can be better answered after a stud}' of the Recent 

 and Tertiary material, where many forms of the genus occur. 



Genus HETEROSTEGINA d'Orbigny, 1826. 



HETEROSTEGINA ANTILLARUM d'Orbigny. 



Heterostegina ant ill arum d'Orbigny, Foram. Cuba, 1839, p. 122, pi. 7, figs. 24-25. 



Specimens were occasionally found in the Montego Bay material 

 which in side view seemed very much like this species in all its char- 

 acters, but in front view were seen to be the young of Orbiculina 

 adunca, where the translucent character of the walls allowed the 

 chamberlets to be seen apparently as markings on the outer wall. 

 No true Heterostegina was found. 



Family MILIOLIDAE. 



Genus CORNUSPIRA Schultze, 1854. 



CORNUSPIRA INVOLVENS (Reuss). 



Opercnlina inrolrens Reuss, Denkschr. Akad. Wiss. Wien, vol. 1, 1849, p. 370, 



pi. 45, fig. 20. 

 Cornvpsira involvens Reuss, Sitz. Akad. Wies. Wien, vol. 48, 1863 (1864), p. 39, 



pi. 1, fig. 2.— H. B. Brady, Rep. Voy. Challenger, Zoology, vol. 9, 1884, p. 200, 



pi. 11, figs. 1-3. 



No specimens are recorded from Cuba by d'Orbigny which could 

 possibly be this species. It is rare, being found at but two of the 

 Jamaica stations at Montego Bay, 1 and 4.
