the number of the eyes in the American form appears to be peculiar, as 
no mention is madè of it in any of the foreign descriptions. In about 
thirty per cent. of the individuals there are more than the normal 
number (two) of eyes, the number varying from three to eight, three 
being the number most frequently occuring. 
A detailed account of this and other American Turbellaria, based 
upon collections made by the Illinois State Natural History Survey 
and submitted to the writer for study, is in course of preparation.—

On the Genus Callisaurus.—Two new species of this genus 
present lateral fringes of the toes. These are not so well developed as 
in the species referred to Uma, but they are sufficiently so to show that 
the latter name must be abandoned, and the species referred to it be 
placed in Callisaurus. Thus, Uma notata Baird, U. scoparia Cope, U. 
rufopunctata Cope, etc., must be called Callisaurus notatus, etc. The 
two new species referred to are both from lower California.

U.S. Natl. Museum, 1889, p. 147. Two series of frontal scales, sepa- 
rated from the rather larger supraoculars by two (or one) rows of 
small scales. Large supraoculars in four or five longitudinal rows, 
the inner row largest, the patch bounded by granular scales ante- 
riorly and posteriorly. Interparietal plate longer than wide. Hind 
leg reaching to front of orbit. Second, third and fourth fingers with 
well-developed fringes, which are weak on the inner side of the second 
and third. External side of second, third and fourth toes with well- 
developed fringes. Femoral pores twenty-three, the scales which they 
perforate in contact with each other. Color above asin O. draconoides. 
Below a blue patch on each side, with three large oblique black spots 
and a trace of a fourth. Total length 200 mm., head and body 87 mm., 
hind leg 72 mm. U.S. N. M., No. 14,895, one specimen. ; 
The differences from C. draconoides are the digital fringes, the larger 
number of femoral pores on adjacent scales, and the three or four 
black spots of the belly patch; the shorter hind legs, and the longer, 
interparietal plate. This species has the larger size of the form C. 
draconoides ventralis. i 
—One row of frontal scales separated 
by small scales from the rather obscure patch of supraoculars. Inter- 
parietal as wide as long. Gular scales subequal. The hind leg ex- 
tended, reaches to and beyond the end of the muzzle. Well-developed 
fringes on the external sides of the fingers and toes, excepting on the
