Source of the data and their presentation. — The following list of 

 proportions and enumerations is based on the 18 specimens in the 

 National Museum collection, which range from 120 to 315 mm. in 

 total length, and from 91 to 240 mm. in standard length. Ten of 

 these specimens (Nos. 84368, 1 18723 (the type), 125939 to 125947,

 in the same order.
