Etymology: Pemia, a quill or pen. 



The dark spot in the axil is a diagnostic mark of this species. The 

 types of milneri and penna are identical. A small specimen in the 

 museum at Cambridge, which may be the type of Poey's Grammateus 

 humilis, belongs to this species. This example is inches long, the eye 

 nearly 4 in head, the depth 2^ in length, and the pectoral as long as 

 head. 



The type of Calamus microps Guichenot is in the museum at Paris. 

 It agrees with Calamus penna in all respects except the size of the eye, 

 which is ^ in head. It is probably not a distinct species. 



Specimens of G. penna are in the museum at Cambridge from Rio 

 Janeiro, St. Thomas, Havana, Camaru, and Rio Grande do Sul.
