Paul Ruthling (1897-1972) was a very special natural historian of Los Angeles County. For example, he was a young man, only 18 years old, when he authored several natural history articles in 1915 and 1916 about reptiles and amphibians in the scientific publication called COPEIA. Featured here is the revised article in LORQUINIA entitled: "A Revised List Of Los Angeles Snakes" which was written in 1917 two years after his original list in 1915 in COPEIA because he discovered that LeConte's Snake also occurred in Los Angeles. Today we know the LeConte's Snake by another name as the Long-nosed Snake. In his opening sentence of his article, Paul states that he found these 15 snakes since 1913, one hundred years ago. This indicates that he was only 16 years old and already had a keen interest in herpetology.

From 1913 to 1917, beginning 100 years ago, Paul Ruthling was very curious about all the amphibians and reptiles of Los Angeles. In the Autumn of 1917 during World War I, Paul departed Los Angeles to go to Mexico, where he would continue his special natural history discoveries with reptiles and amphibians found there. He affiliated himself with the national museum of Mexico, and also collected species for the American Museum of Natural History in New York. He discovered species new to science while in southern Mexico. A few years later he would return to the U.S. in New Mexico and then later in Arizona. The hope is that Los Angeles residents will welcome the recovery of amphibians, both salamanders and frogs to uplands and vernal wetlands at the baseball fields of the Ballona Wetlands State Ecological Reserve. This geographic area is very special habitat that is in need of preservation and to recover the Long-nosed Snake (aka LeConte's Snake). 1
