ACANTHODACTYLUS SCUTELLATUS. 161 
specimens of A. partialis this also occurs, however, on a more limited area, so that 
the difference between the two in this respect is only one of degree. The digital 
denticulations are feebly developed, as in A. vulgaris ; there are only two entire supra- 
oculars, as in that species ; and, as occurs generally in it, the subocular borders the 
lip. All of these characters, however, are shared more or less by A. partialis, so that 
the differences between the three are ill-defined.
