HATCHING PERIOD 



"Eggs laid early morning of May 21, 192 1, hatched early morning of May 

 24, 1921, or three days later." Eggs "collected in the field in the morning of 

 May 22 after the laying of the night of May 20-21 hatched the night of May 

 23-24" or three days later. Eggs "laid the night of June 4-5, 192 1, after mid- 

 night were hatched by June 7, 6:00 a. m. or three days after ovulation." 

 The eggs laid by one captive pair July 4, 192 1, did not hatch at all. Doubtless 

 captivity, infertility, restricted quarters or laying without male may have 

 caused it. 



MATURE TADPOLE 



Color description from life (July 8, July 16, 1921). Upper parts of body 

 olivaceous black to dull greenish black. Throat on either side below eye 

 pomegranate purple. Belly on sides and across breast light vinaceous purple; 

 center of belly solid sulphur-yellow. Chin clear with very little or no black 

 dots. In younger tadpoles general color light yellowish olive or grayish olive. 

 All over upper parts are fine light grayish vinaceous or light vinaceous fawn 

 dots and on the muscular part of tail but not on the crests. These dots become 

 larger on dark upper eyelid and give a conspicuous arrangement. In half- 

 grown tadpoles a cream-colored ring under the eye and extending backward 

 on either side of back for a distance. In very young tadpoles the ring is almost 

 complete about the eye but not on the back. This ring faintly present in 

 mature tadpoles and extends backward on to the base of the musculature of 

 the tail. Under the eye it is warm buff, on body buffy brown and cartridge 

 buff or tilleul buff. 



Tail. Beginning at body there runs along musculature for one-half or 

 more of its length a white, cartridge buff or pale cinnamon pink stripe marked 

 off by the dark brown or black ground color of the upper half of the muscula- 

 ture and lower crests with prominent large spots black in younger specimens, 

 and clusters of mouse gray on mature tadpoles. The tip of tail (both upper 

 and lower crests) clear of spots. Area of crest next to musculature clear in 

 upper. 



General appearance. Tadpole small (36 mm.) full and deep bodied. Tail 

 medium to fairly long, tip acuminate and very pointed. Tail with a promi- 

 nent flagellum the dorsal and ventral crests of which are usually colorless. 

 Tail deep and dorsal and ventral crests well developed. The dorsal crest may 

 exceed the musculature in depth and extends on to the body to the vertical of 

 of the spiracle or half way between spiracle and eye. Spiracle sinistral, 

 directed more backwards than upwards, far below the lateral axis and visible 

 as an elliptical opening. Eye on the lateral axis, in dorsal aspect on the lateral 

 outline and in consequence visible from the venter. Anus dextral, very near 

 the level of the edge of the lower crest. Muciferous crypts indistinct. 



Mouth parts: Teeth 2/3. Upper labium fringed with a continuous row of 

 labial teeth; the papillae extend above and inwards beyond the end of the 

 upper fringe for about 4/1 1 to 2/5 of the length of the upper fringe. The end 

 of the second row usually is even with the end of the upper fringe. The horny
