PEROPUS MUTILATUS (Wiegmann). 



The skin of this species is so thin and tender that a specimen may 

 scarcely be caught without mutilating it. The struggles of the animal 

 in one's fingers result in tearing great rents in the skin, and it is 

 difficult to retain one between the tips of the forceps. The woimds 

 thus made bleed but very Uttle, and it appears that the fragile skin, 

 like the easily broken tail, aids the animal at times in escaping from 

 an enemy. 



In life the under parts are more or less tinted with yellow, very 

 bright in some examples, almost absent in others. The color is 

 more intense on the hind legs and belly. 



Eggs of the species, easily distinguished from the others, were 

 secured and successfully hatched. Specimens of both the eggs and 

 young were lost in transportation, and no description remains. 



Honolulu; Waimea, Kauai; Puako Bay, Hawaii. 



HEMIPHYLLODACTYLUS LEUCOSTICTUS Stejneger. 



In life the whole body is slightly tinted with pink. The mider 

 parts from the throat posteriorly, including the legs, are pale yeUow. 

 In the younger specimens the tail is pale orange beneath. Where the 

 tail has been reproduced, the yellow color stops short, the lately 

 acquired part being dark beneath. The throat is spotted with dusky. 



Eggs measuring 5.7 to 6.6 millimeters, smaller than those of other 

 species, found under a bit of loose bark, proved on hatching to belong 

 to this species. They were slightly indented and fu-mly cemented 

 together. The young, just hatched, measured 29 millimeters in 

 length; snout to tail, 15.5. They soon shed the epidermis, exhibiting 

 the colors of the adult. They are precocious like the young of other 

 forms.

Family SCINCIDAE. 



LEIOLOPISMA NOCTUA (Lesson). 



One specimen was seen at Honolulu. 



EMOIA CYANURA (Lesson). 



Specimens collected by the writer exhibit two types of coloration * 

 one with a well-defined, narrow, light band extending from the pos- 

 terior edge of the rostral plate to at least the middle of the body; the 

 other without a distinct median band, which if at all developed never 

 extends on the head. 



1 stejneger (Proc. U. S. Nat. Mus., vol. 21, 1899, p. 808) discusses the color variation of this species, and 

 Wemer (Zool. Jahrb. Syst., vol. 14, p. 384) describes some dark-colored examples from Molokai as Lygosoma 

 cyanurum schauinslandi. The figure in Zoology of the Voyage of the Coquille (pi. 4, fig. 2) is of interest in 

 this connection.
