Here again we find the same general facies which was first noted at 
Cloudcroft. About 30 miles west of Roswell on the Lincoln Road, Mr. 
Richardson obtained a few fossils which I have identified as Productus Leeif, 
Productus subhorridus?, Productus Mexicanus? and Composita? sp. The 
stratigraphic horizon of the last is considerably higher than the preceding 
and occurs in beds which are apparently the continuation of the upper strata 
in the Guadalupe Mountains. Insofar as it goes this fauna presents the same 
facies as those of lower horizon farther west. Now, it is possible that among 
the varied Producti grouped under P. Mexicanus? and P. subhorridus? 
there may be some which might be identified as P. occidentalis of the Capitan 
limestone (P. Mexicanus itself was first described from the Capitan) or 
P. Popei of the dark limestone or P. Texanus of the Delaware Mountain 
formation, but it is apparent that the Guadalupian fauna in a characteristic 
form is not indicated by our collections in the northward extension of the 
Guadalupian rocks, all the variety, all the peculiar species which gave color 
to it being absent. Our collections, especially from the higher horizons, are 
unfortunately meager and may give a perverted view of the fauna as it really 
occurs, but the evidence is such as to demand a consideration, if not the 
adoption, of the hypothesis that the facies of the Guadalupian fauna is a 
regional matter denoting not time relations but geographic relations. 
There is one more collection made by Mr. Fisher from a limestone in the 
“Red Beds” northwest of Roswell which represents a still higher horizon 
than any of the foregoing. The fossils are abundant but represent only two 
species, Pleurophorus? aff. subcostatus and Schizodus aff. ovatus. The 
Schizodus may be the same species which at Cloudcroft I identified as S.
