Description of larva. — Greatest length of head-and-body, 18 milli- 
meters; of tail 29 mm.; length of head-and-body contained 1.2 to 1.8 
times in length of tail; external nares midway between tip of snout 
and orbit ; eyes well up on top of head ; interorbital space 5 to 9 times 
in length of head-and-body; spiraculum sinistral, aperture directed 
backward and upward, center of aperture decidedly behind midpoint 
of body; anus dextral; greatest depth of tail (over fins) 3.3 to 4.2 in 
its own length; height of muscular portion of tail 4.2 to 6 in head- 
and-body length. 
Labial teeth in % rows, first complete across entire mouth region, 
second to seventh inclusive interrupted medially, the successive rows 
progressively shorter and shorter ; eighth row shorter than first, and 
interrupted medially, ninth to twelfth complete, successively shorter ; 
papillae in single row on lateral and ventral borders of mouth region 
(% II). 
An example of Dana hoylii hoylii, with all four legs fully developed 
but with tail not yet resorbed, which was collected in San Pablo Creek, 
Contra Costa County, on August 7, 1922, was colored as follows: 
Ground color of back deep olive, paling posteriorly and laterally 
through citrine drab, and becoming dark olive buff on exposed surfaces 
of legs ; a dark Y-shaped patch of dusky across middle of upper eye- 
lid and interorbital space ; snout and side of upper jaw mottled with 
brownish black ; back and sides with scattered spots of blackish, each 
about 2 mm. in diameter and each with a central light dot of wood
