2 20 PATAGONIAN EXPEDITIONS: ZOOLOGY. 



can be told apart at a glance notwithstanding their general similarity, as 

 the young of the latter have the black dorsal markings invariably inter- 

 rupted by the three distinct dorsal pale lines, while in the latter there are 

 no distinct lines and the black markings are continuous across the back. 

 Moreover, L. kingii has noticeably larger and flatter head-shields, and 

 much smaller dorsal scales.

 As Mr. Hatcher obtained only two specimens of this species, it is prob- 

 ably permissible to conclude that it did not occur commonly in the locali- 

 ties where he did most of his collecting. These specimens were in a jar 

 with five/-. /^///^// taken "among mate negra bushes." As the latter 

 almost certainly were collected north of the Rio Santa Cruz, the L. bibronii 

 probably also came from that part of his route in 1898. 



The specimens present no features of special interest. The dark spots 

 on the upper surface show a distinct tendency to fuse into longitudinal lines.
