 L. lineomaatlatus is probably the northern representative of L. itiagel- 

 lanictis. The latter is recorded fi-om Tierra del Fuego and ft^om the Straits 

 of Magellan. According to Andersson both forms were collected together 

 at Puerto Gallegos by the Nordenskiold expedition, in 1895. 



One specimen only out of the 40 collected by Mr. Hatcher has a defi- 

 nite locality assigned to it, as stated above, viz., the one from "The 

 Salinas " near mouth of the Rio Santa Cruz. The two L. kingii in the same 

 jar from "north of Rio Santa Cruz," were also collected in March, 1898, 

 and the uniformity of the series makes it appear probable that all were 

 secured in the same neighborhood, i. e., between Santa Cruz and Lake 

 Buenos Aires. According to Hatcher they are common everywhere on 

 the pampas up to an altitude of 3,000 feet. This statement includes Lio- 

 Iccmus JiatcJieri also, and as the two species are very much alike super- 

 ficially, it remains doubtful whether they occur together or perhaps at dif- 

 ferent levels. 



The series brought home by Mr. Hatcher shows great uniformity in 

 character, and the young are practically like the adults. The greatest 

 variation appears to be in the coloration of the underside, which is more 

 or less marbled with dark gray lines, most distinctly on the throat. Many 

 specimens are nearly uniform whitish underneath, while on the other hand
