THE SPECIES OF AEGLA-— SCHMITT 433 



The Museum of Comparative Zoology, Cambridge, Mass., through 

 the kindness of Dr. Fenner A. Chace, Jr., also lent me all their Aeglas 

 for study. One specimen of a lot from Santiago, Chile, was selected 

 as the neotype of A. laevis. There is no certainty that the original 

 type is extant or in the Paris Museum, where it was believed to have 

 been deposited. Another specimen, from Talcahuano, Chile, has 

 been made the type of a new subspecies of A, laevis bearing the 

 subspecific name talcahuano. 



From the late Dr. Carl H. Eigenmann, of the University of Indi- 

 ana, the National Museum received certain Chilean Crustacea, which 

 included a new species, A. abtao, and several specimens of the long- 

 lost A. dentlculata of Nicolet. 



In the type collections of the United States National Museum, in 

 addition to A. castro^ yarana^ yrado^ odebrechtii (neotype), coiv- 

 cepcionen-sis, and abtao, there are the types of five other new forms : 

 A. platensis, frarwa, odebrechtii paulensis, neuquensis, and 

 riolimayana, 



The late Dr. Florentino Felippone, of Montevideo, contributed 

 specimens of Aegla from Uruguay to the United States National 

 Museum collections on several occasions, as did also Alberto Tre- 

 moleras, of the same city. Finally, I received additional very help- 

 ful material from Dr. Carlos E. Porter, of Santiago, collected in 

 part by Dr. A. Santa Cruz, of Concepcion, Chile; from Dr. Carlos 

 Moreira, of Rio de Janeiro, collected by Dr. G. Kuhlmann at Blu- 

 menau, Santa Catharina, Brazil ; and from Dr. Paulo Sawaya, of the 

 University of Sao Paulo. 



Through the kindness of Henry W. Fowler, of the Academy of 

 Natural Sciences of Philadelphia, and G. Ayres Coventry, research 

 associate in charge of Crustacea, I had the opportunity of examining 

 seven Aeglas (four lots) contained in the Academy's collections: (1) 

 Three females collected by "Dr. Wilson" in Chile, which proved to be 

 A. papudo; (2) two females of A. laevis received years ago from the 

 Smithsonian Institution, for which regrettably there are no locality 

 data or any record at the Institution of this particular sending; (3) 

 a dried specimen of what is unmistakably A. odebrechtii^ "du Bresil. 

 Donni par M. M. Derreaux"; and (4) one of Dana's Wilkes Exploring 

 Expedition Aeglas with an original printed Expedition label filled out 

 presumably by Dana himself — ^'•Aeglea laevis. Chili." 



I am immeasurably indebted to the Walter Rathbone Bacon 

 Scholarship of the Smithsonian Institution, which enabled me to visit 

 South America personally to collect some of the specimens upon 

 which this paper is based and to establish the many helpful contacts 

 that made it possible to gather the most comprehensive representation 

 of the genus Aegla that has ever been in anyone's hands for study at
