Plate 14, figures &-10 



Peneroplis planatus Cushman, Proc U. S. Nat. Mus., vol. 59, 1921, p. 75, 

 pi. 18, fig. 9 (not Fichtel and Moll); Publ. 311, Carnegie Instit. Wash- 

 ington, 1922, p. 79. 



Peneroplis pertusus, var. planatus Woodward, The Observer, vol. 4, 1893, 

 p. 77. 



Test small, very greatly compressed, early portion planispirally 

 coiled, usually partially e volute, later portion broadening, forming a 

 flaring test; chambers distinct, long and low; sutures very distinct, 

 depressed; wall finely pitted but not striate; apertures in the central 

 line of the apertural face. 



Length, usually less than 1 mm., often much less. 



Holotype. — (Cushman Coll. No. 4840), from Alontego Bay, Jamaica. 



This species is next to P. proteus the most common in the West 

 Indian region. It occurs at numerous stations off the Tortugas and 

 the Florida Keys, at Bermuda and Jamaica. It is probably widely 

 distributed in the general West Indian region. 



Peneroplis planatus, so far as I have seen, does not occur in the 

 western Atlantic and is apparently replaced by this species. 



Karrer described a variety of P. planatus as var. laevigata from the 

 Miocene of Kostej , but it is not the same as the West Indian species. 

 I have topotypes of Karrer's variety for comparison. Brady's speci- 

 mens, figured under this varietal name,^ are from Bermuda and 

 probably are P. hradyi.
