Remarks. There are 59 specimens in all. Cl. ranges in 2 from 2°75 to 
725 mm.and in ¢ from 2°75 to 8:25 mm. None of the 2 specimens are

an adult appearance. The largest g has U.l. 8°25 mm. and C.b. 11°5 mm.,

Of 50 specimens 35 (12 ¢ and 23 ? ) have the right hand, and 15 (7 ¢ and 
8 ¢ ) the left hand, the more massive. Heller also found that in his examples
