M Determination of the author of this name is perhaps an academic matter. Heretofore Wolterstorff has 

 generally been considered as the author, since he on page 132 of the same publication, in a separate article 

 "Zur Systematik und Biologie der Urodelen Mexikos" names and describes an "Ambystoma tigrinum subsp. 

 velascoi Wolt." However, in an article ("Untersuchungen iiber die Lebensgeschichte mexikanischer 

 Ambystoma-Arten") which precedes Wolterstorff's Lafrentz (p. 105) cites the name "Ambj/sfoma tigrinum 

 velascoi subsp. n." and proceeds to describe the race well enough to permit at least recognition and retention 

 of the name. Neither author, it may be noted, cites a type. Technically, for that reason, neither description 

 need be accepted, although we hesitate to follow the rules so closely. 



However, on page 145 a "Richtigstellung" states that "Ambystoma tigrinum velascoi subsp. n." should read 

 "Ambystoma tigrinum velascoi Wolt." 



There can be no question that the original proposal of ^. t. velascoi is in Lafrentz's article. We believe, 

 moreover, that he, not Wolterstorff, should be regarded as the author — the correction on page 145 notwith- 

 standing—for the following reason. The description was, obviously, written by Lafrentz; the treatment is 

 much different from that which Wolterstorff gives, and there is no indication whatever that it is a quotation 

 from any ms. of Wolterstorff. Although it may be "clear from the contents of the publication that some 

 other person . . ." (i. e., in this case, Wolterstorff) ". . is responsible for said name . . ", definitely it is 

 quite apparent that he is not responsible for ". . . its indication, definition, or description." (All quotes 

 from art. 21, Intern. Rules Zool. Nomen.)
