any connection with the division of reptiles), six specimens under the number 119S0. 

 Specimens -were at that time numbered by lots and not individually. The latter practice 

 was inaugurated by me wlicn I took charge in 1889. The original entry gives ' Cerros 

 Island' as the locality and ' L. Belding ' as the collector. (2). The entry in Yarrow's 

 check list of 1882, p. 45, giving ' La Paz, Lower California,' as the locality for the six 

 specimens, 11980, and the collecting date as February, 1882, is a clerical error. There 

 is nothing in the record book to indicate that this locality is correct, and, as noted, 

 the specimens were already in the Museum In November, ISSl. (3). When I overhauled 

 the collection in 1890 I discovered that the six specimens of 11980 from Cerros Island 

 belonged to two different species ; the one, which was a true Verticaria, was given the 

 original number, 11980 ; the other five, representing an undescribed species of Cnemi- 

 dophorus, were reentered and given the new individual numbers, 15.590-15600, inclusive, 

 No. 1D59G being designated as the type; typo locality, Cerros Island. (4). In 1894 I 

 discovered that certain specimens of Verticaria differed from the typical V. hyperythra. 

 I described the new form as V. 'beldingi and designated No. 11980 as the type ; type 

 locality, also Cerros Island. (5). Cope's (1900) account was written many years before, 

 apparently before the description of V. teldinfji, the existence of which was probably 

 overlooked by him. The enumeration of the six specimens as 11980 is only copied from 

 Yarrow's check list with the locality corrected. (6). There is nothing theoretically im- 

 probable in V, hyperythra heldiiigi and C. lahialis living in the same habitat. They are 

 sufficiently distinct for that. It is true that subspeciflcally distinct forms are not likely 

 to persist as such in the same habitat for any length of tiuio (unless isolated by some 

 physiological barrier), but that 'law' certainly has no application in this case. (7). The 

 fact that these species have not been found on Cerros Island by recent collectors is 

 purely negative evidence. (8). On the other hand I can not guarantee that the original 

 entry is correct as to the locality of Cerros Island, but at the present time I see no 

 reason for doubting it. It is not good practice to exchange one uncertainty for another."
