New Mexico Distribution--Wu (1993:91) has reported Catinella vermeta from several northeastern and north-central
counties in N e w Mexico, Union, Colfax, Mora, San Miguel, and R i o A r r i b a .

Dr. Dorothea Franzen has dissected some succineids
collectedbyMetcalffromthelocalityNNW ofRadiumSprings and from San Simon Cienega, Hidalgo Co. She has assigned these specimens to C. vermeta. In addition to the assignments madetoC vermeta,Wu (1993:91,93)listedtwootherrecords, whichheassignedto"Catinellasp. 1"(4specimensfromUnion Co.) and "Catinellasp. 2" (1specimen from Otero Co.). Hubricht (1985) does not map any species of Catinella other than Catinella avara (considered by him, as noted above, to be a prior synonym of C. vermeta) as occurring any closer to N e w Mexico than easternOklahoma.
Family Helicarionidae Genus Euconulus
Euconulus fulvus (O. F. Müller, 1774, as Helix). V e r m i u m etc. (see Cionella lubrica for full citation), 2:56. T.L.;Fridrichsdal,Denmark. (brownhive)
General Distribution--This species has an exceedingly broad range, including much of the Palearctic (Europe and northern Asia) and Nearctic (North America) zoogeographic regions.IntheNew World,itrangesfromAlaska,Canada,and GreenlandsouthtotheconterminousUnitedStates,whereitis found in the northeastern quadrant and in western states. Itis not found in the Great Plains region at present, but occurs as a Pleistocene fossil from Nebraska and Iowa, south to northern Texas (Hubricht, 1985:Map 331).
New MexicoDistributionandHabitat--Euconulusfulvus is widespread and c o m m o n in all the forested mountains that reachintotheTransitionZone. Collectionsofleaflitterfrom the
Transition and Canadian Life Zones commonly contain this species.

Genus Nesovitrea
Nesovitrea hammonis electrina (A. A. Gould, 1841, as Helix). Report on the Invertebrata of Massachusetts, comprising the Mollusca, Annelida and Radiata, p. 183, Fig. 111. T.L.: shores of Fresh Pond, Cambridge, Massachusetts. (amber glass)
General Description--The name electrina has been used
at the species level for North American representatives of this
taxoninmuchoftheliterature.BequaertandMiller(1973:145)
consideredthespecieshammonis toincludeboth Palearcticand
Nearctic representatives. They retained the name electrina for
Nearctic populations, but relegated itto subspecific level. So
construed, N. hammonis isexceedingly widespread, occurring
in the Palearctic from Iceland and the British Isles, through
northern Eurasia to Japan and Kamchatka, with the electrina
subspecies found from Alaska southward to the northern half of
the conterminous states, and southward in the Rocky Mountains toNew MexicoandnorthernArizona. -

Itreasonably could be regarded as one of a number of species that extended southward along the Rocky Mountains in past times and, at present, m a y be a Pleistocene relict, towards the south.
