TEIIb LlZAinJS OF TliE GENUS CXEMIDOPHOItUS 33 



Cneni'idoplioi'UH espeuti, dcscrilu'd from Old Providence Island by 

 Boulen«i;er (1885), has never been clearly diagnosed. An exairiina- 

 tion of subsequent specimens from this island shows that espeutl 

 differs little from the lemniscatus of other phices. The description 

 ''olive above. Avith a broad liLditer dark-edged band from the occiput 

 to the base of the tail " excellently tits a number of examples of 

 leinniscafus from Venezuela in the United States National Museum, 

 as well as the tj'pe of (' ncm/dophorus Jemniscatus ga'tgel and other 

 si)eciniens. Moi'ever. younii- examples from Old Providence Island 

 ha\-e been found to be lined, and the early loss of stripes is some- 

 times seen in mainland examples. Furthermore, the four supraocu- 

 lars, five parietals. and peculiar keeling of the caudal scales attributed 

 to c.speuti are all common features of lemniscatus. Since constant 

 distinguishing characters arc not evident, espeufi is considered as 

 identical with that form. 



Cnemidophorus h iiin/sc(tfi(s (jit'KjeK described by Kuthven (1915) 

 from Colombia, was said to differ from lemniscatus in its larger size, 

 fewer femoral pores, gieater Avidth of the parietal shields, and 

 fewer parietal-postorbital granules. 



The maximum size of (jaige'i Avas listed as 100 mm. (snout to anus) 

 as oj^posed to the 78 nun. of letnniscatus, but a specimen of the latter 

 from British Guiana has been found to have a body length of 85 mm. 

 (A.M.N.H. No. 8734). In the latter place, British Guiana, a number 

 of specimens are found with a body length of over 80 nun., so the ap- 

 pearance of the large specimen cited above can not be regarded as 

 abnormal or accidental. In Venezuela a specimen Avith a body length 

 of 100 mm. Avas taken at Cariquito (A.N.S.P. No. 18()<)) : another 

 from Rio Chico measured 88 mm. An example from Old Providence 

 Island (U.S.N.M. No. 113877) has a body length of *.)0 mm., and 

 larger specimens Avill probably appear in any general collection of 

 /e/nruscatus. These data shoAV that the size difference is not con- 

 sistently geographic, and so is of little diagnostic value, (ireater 

 size in certain regions may be the result of highly favorable bionomic 

 conditions as nuiintained l)y Kuthven himself (15)00) in regarding 

 ihe large '"'' scalaris''' Avliich occurs near Tucson. Arizona, as a syno- 

 nym of the nuich smaller " f/u/a/'/s'' ( — perpJexus) of the region. 



The femoral pores of (jalgei Avere said to range from IG to 24 in 

 number and those of lemniscatus from British Guiana from 2)3 to 29. 

 axerage 26. Ruthven's data Avere secured from 48 sj)ecimens from 

 British Guiana. The examination of a like numl)er from the same 

 political area. Avliile at the Amei'ican Museum of Natural History, 

 has shown a range of from 21 to 27 femoral ])ore,s. a\erage 23.3. 

 Here, also, the differences ai)[)ear to be less than those hitherto cited.
