  specimen 
  in 
  the 
  U. 
  S. 
  National 
  Museum. 
  In 
  the 
  cx])lanati<m 
  of 
  tlic 
  plate 
  (pi. 
  1, 
  fig. 
  6) 
  the 
  

   specimen 
  is 
  indicated 
  as 
  "tjpe" 
  with 
  the 
  dimensions 
  of 
  the 
  L'. 
  S. 
  National 
  Museum 
  specimen. 
  

   Therefore, 
  the 
  word 
  "type" 
  in 
  the 
  explanation 
  should 
  be 
  deleted. 
  Accordingly, 
  the 
  type 
  

   data 
  in 
  Oldroyd 
  (1927) 
  should 
  be 
  corrected. 
  

  

  The 
  type 
  of 
  L. 
  varicgata 
  (Carpenter) 
  came 
  from 
  Cape 
  San 
  Lucas. 
  From 
  the 
  explana- 
  

   tion 
  of 
  the 
  use 
  of 
  the 
  name 
  in 
  Arnold, 
  the 
  discussion 
  probably 
  belongs 
  to 
  L. 
  ine.ricana 
  Dall 
  

   and 
  Bartsch 
  (1909). 
  This 
  interpretation 
  has 
  been 
  followed 
  by 
  Grant 
  and 
  Gale 
  (1931, 
  p. 
  865). 
  

   Burch 
  (1946, 
  p. 
  20) 
  believed 
  that 
  all 
  the 
  forms 
  mentioned 
  represent 
  one 
  species. 
  In 
  that 
  

   case 
  the 
  species 
  would 
  also 
  have 
  to 
  be 
  accounted 
  for 
  in 
  the 
  diagnosis 
  of 
  the 
  Pleistocene 
  of 
  

   San 
  Pedro 
  (Arnold).
