Since the completion of this paper, which was written early in 1Q17, 

 the arbitrary boundary line between the Oligocene and the Miocene 

 has been shifted a notch or two lower in the time scale, thus placing 

 the La Cruz marl of Cuba, which had been regarded as Oligocene, on 

 the Miocene side of the boundary. The fossils from the La Cruz marl are 

 referred to the Oligocene instead of to the Miocene. This error is one 

 of nomenclature, not of correlation. 



The specimen from Anguilla figured on plate 2, fig. 3, and identified 

 as Orthaulax pugnax (Heilprin) has proved, on further study, to be an 

 undescribed species. Excellent specimens of the same species were 

 recently obtained at several widely separated localities in Santo Do- 

 mingo, and two fine casts come from the Island of St. Croix. As Miss 

 C. J. Maury had described in manuscript an Orthaulax from Aguadilla, 

 Porto Rico, which may be this species, I am refraining from giving my 

 specimens a name until after her paper has been published. 



5. The Crustacea studied are the Decapoda in the Vaughan collec- 

 tion from Anguilla and Antigua, the Gabb and Maury collections from 

 Santo Domingo, and one specimen of doubtful origin. Thirty species 

 are listed, but only 22 are specifically identified. Three new genera 

 are described. C. WyThe Cooke. 



ANTHROPOLOGY. — A structural and lexical comparison of the Tunica, 

 Chitimacha, and Atakapa languages. John R. Swanton. Bur. 

 Amer. Ethnology, Bull. 68. Pp. 56. 19 19. 

 The Tunica, Chitimacha, and Atakapa languages were made the 

 bases for the Tonikan, Chitimachan, and Attacapan linguistic families 

 or "stocks" in the original classification of American languages north 

 of Mexico by J. W.. Powell. Even in Powell's time a reduction in the 

 number of recognized stocks took place, and the process of reduction, 

 or attempted reduction, had been markedly accentuated in recent 

 years. The author believes he has adduced sufficient evidence in 

 the present bulletin to prove the genetic relationship of the three lan- 

 guages considered. J. R. S.
