THE SPECIES OF AEGLA — SCHMITT 439 



Aegla, it must be distinct, even if not a true Galuthea as Smith 

 suspected. 



Apprised by Wierzejski (1897, p. 1) of the shortcomings of his 

 earlier note, Nobili (1898, p. 6) hastened to publish an emendation. 

 In this he pointed out that Wierzejski (1892) himself had been 

 anticipated by Lucas (1876), and that Berg's note (1892) appeared 

 the same year as Wierzej ski's. 



Almost on the heels of this note of Nobili's (1898), not quite three 

 months later, Berg (1898, p. 7) reprinted verbatim his notes of 6 

 years before. To these he added references to the remarks of Nobili 

 (1896) and Wierzejski (1892; 1897), and three new Argentine rec- 

 ords: the provinces of Salta and Cordoba and Neuquen Territory. 



Strictly in agreement with the pronouncements of Wierzejski 

 (1892) and Berg (1892; 1898), Ortmann (1898, p. 1149), under the 

 family Aegleidae [now better Aeglidae], tersely stated, "Monotype 

 Familie, von der Gattung Aeglea Leach gebildet, die einzige Art 

 {A. laevis Latr. Taf. Ixxiv, Fig. 1**) in Siid-Brasilien, Argentinien 

 und Chile besitzt, wo sie in Siisswasser, besonders in Gebirgsbachen 

 lebt." As the figure cited appears to have been copied directly from 

 Cuvier (1837, pi. 47, fig. 3), quite naturally my comments on the 

 original (p. 435) apply to Ortmann's black-and-white reproduction 

 of it. 



Following Cunningham (1870, p. 495), who merely mentions 

 A. ''''laevis^'' as having been "collected in a fresh-water stream in the 

 neighborhood of Valparaiso," no further references to Aegla from 

 Chile appeared in literature so far as I am aware, until that of 

 Doflein (1901, p. 135). He added a new locality to its range in that 

 country : Lake Llanquihue, near Puerto Montt. His A. Haevis'''' may 

 be A. abtao. 



Carlos Moreira (1901, pp. 21-23, 84) with fresh material that he 

 had collected in the State of Santa Catharina, Brazil, in his invalu- 

 able work on the "Crustaceos do Brazil," fully demonstrated the 

 distinctness of the A. odebrechtii of Fritz Miiller. At the time, un- 

 fortunately, he believed it to be synonymous with Girard's Chilean 

 A. intermedia. 



In spite of Moreira 's able presentation of the case, Ortmann (1902), 

 in his extremely interesting paper on "The Geographic Distribution of 

 Freshwater Decapods and Its Bearing upon Ancient Geography," 

 continued to insist that the genus was monotypic. This stand, which 

 also had been emphasized by Berg (1892; 1898), seemed to close the 

 door on further taxonomic investigations. Most, if not all, subse- 

 quent work has apparently been undertaken under the impression 

 that there was only one species of Aegla^ for it has been confined 



"**A. odebrechti F. Miill. is hiervon nicht verschieden."
