Hoffmann" Before the publication of Findley's monograph, Speciation of the Wandering Shreiv (1955a), the Sorex vagrans complex was thought to consist of at least three closely related species: Sorex vagrans, S. obscurus, and S. pacificus. Jackson (1928) separated these species on the basis of size and pelage color; throughout much of the Pacific Northwest at least two of the taxa can be collected at the same localities. However, in the northern Rocky Mountains, especially in western Montana, vagrans and ohscurus are so similar in size and pelage color that mammalogists found them impossible to distinguish (Clothier, 1950; R. S. Peterson, pers. comm.; P. L. Wright, pers. comm. ) . Findley ( 1955a ) interpreted these similari- ties as an indication that barriers to interbreeding between vagrans and obscurus had broken down along much of their zone of contact. He speculated that the two forms had a connnon origin prior to the Wisconsin glaciation and had diverged while isolated from one an- other during the final glacial period. Sorex obscurus appeared to intergrade also with Sorex pacificus (including S. yaquinae) in western Oregon. Findley concluded that the three species were in fact one — a complex ring of overlapping subspecies to which he applied the name of the earliest described form, Sorex vagrans.

Findley distinguished obscuriis from vagrans as subspecies, but his descriptions do not pemiit easy identification. Mammalogists working with shrews from the Rocky Mountains and other areas where the two fonns differ subtly, tended to lump vagrans and ohscurus together as "Sorex vagrans'^ with the unfortunate result that important differences between the two were obscured (e.g., Brown 1967; Hoffmann and Taber, 1960; Ingles, 1961; Spencer and Pettus, 1966; in all cases the shrew identified as vagrans was actu- ally ohscurus ( Fig. 1 ) . Findley 's revision was greeted cautiously by some. Johnson and Ostenson (1959) suggested that the biological relationships among the subspecies of Findley 's Sorex vagrans were too poorly known to justify his sweeping revision of the nomen- clature, and proposed that the basic framework of Jackson's 1928 classification be upheld until further studies could be made. Findley's conclusions were based on his interpretation of the nature of character convergence between vagrans and ohscurus in the northern Rocky Mountains (1955a: 12-13, 44-45, and 54-55). We attempted to locate "pure" populations of the two supposed subspecies, in order to define their differences and clarify their morphological and ecogeographic relationships (Hennings, 1970). We found differences in the structure and pigmentation of the up- per incisor teeth and in cranial dimensions which clearly separated vagrans and ohscurus, and confirm their specific integrity, as will be shown. Sorex monticolus, Merriam 1890, long considered a synonym of Sorex vagrans, is the oldest available name for the species previ- ously known as S. ohscurus Merriam, 1895. The familiar name is applicable only to the most widely distributed subspecies, S. m. ohscurus (Fig. 2). Sorex pacificus is morphologically distinct from Fig. 1. — Sorex monticolus ohscurus, Sierra Nevada, Fresno Co., Calif.

REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 3 S. monticohis (=S. ohsctinis), but as Findley observed, there ap- pears to be a narrow zone of hybridization between the two taxa. We discuss certain taxonomic problems which may arise as the nature of their relationship becomes more fully understood. In the rest of this paper we use the names Sorex monticohis (=zol)scurus), S. pacificus and S. vo grans. Materials and Methods Hennings collected, at key localities in western Montana, 94 Sorex V. vagrans and S. nionticolus obscnrus, using snap-traps and sunken cans (Hennings, 1970). Subsequently, we also examined 2,502 additional specimens, including all subspecies of Sorex va- grans, S. monticohis and S. pacificus (including S. yaqiiinae), as well as S. durangae, which Jackson (192S) included in the Sorex vagrans group, and S. trigonirostris, which he allied with S. ornatus (Fig. 2). Specimens were borrowed from the following collections (see also Specimens Examined, Appendix): Brigham Young Uni- versity Life Sciences Museum ( 13YU ) ; California Academy of Sci- ences (CAS); California State University, Long Beach (CSLB); Carol Terry (CT); Dartmouth College Museum"(DCM); Harvard University, Museum of Comparative Zoology (MCZ); Michigan State University, The Museum (MSU); Montana State University, Bozeman, Department of Zoology (MSUDZ); National Museum of Natrual History (USNM); National Museum of Natural Science, Ottawa (NMC); San Diego Natural History Musevmi (SDSNH); Southern Oregon College (SOMNH); Stanford University Collec- tion, at the California Academy of Sciences (CAS-SU); University of Alberta, Museum of Zoology (UAMZ); University of British Co- lumbia Vertebrate Museum (UBC); University of California, Berke- ley, Museum of Vertebrate Zoology (MVZ); University of Kansas, Museum of Natural History (KU); University of Montana, Zoolog- ical Museum, Missoula (UM); Universidad National Autonoma de Mexico (UNAM); University of Utah (UU); Washington State University, Charles R. Connor Museum (CRCM). In the initial phase of the study 40S post-juvenile S. v. vagrans and 115 S. monticohis ohscnriis from the northern Rocky Mountains and Columbia Plateau regions were selected for statistical analysis. Specimens were identified by body measurements and by tooth characteristics described below. Six cranial dimensions described by Findley ( 1955a : 5 ) , plus cranial height, were measured with Helios metric dial calipers. Age was determined by Rudd's (1955a) subjective toothwear method. Data from the largest homogeneous population of each species were grouped by age and month of capture and analyzed statisti- cally. ( Sex differences in Sorex have no significant effect on cranial 4 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 5 morphology; see Rudd, 1955a.) Of the six measurements used by Findley only one, maxillary tooth-row length, varied significantly with age. Cranial height varied according to the patterns noted by Dehnel (1949), Pucek (1955, 1957), and Dapson (1968). (See dis- cussion in Hennings, 1970). Hennings ( 1970 ) grouped specimens into several geographical populations, the cranial dimensions of which were compared sta- tistically. For this report we have regrouped some of the smaller samples (Fig. 3), and will compare data from only the three most variable measurements; condylobasal length, palatal length, and least interorbital breadth ( Fig. 7, A ) . Pelage color and body meas- urements were not analyzed in detail (but see Hennings, 1970).

Analysis of Morphological Characters Jackson (192S) distinguished Sorex ohscurus from Sorex vagrans on the basis of total length - ohscurus being 110 mm or greater and vagrans less than 110 mm. Figure 4 is a review of total length measurements from shrews collected in a number of regions in the Pacific Northwest. Sorex monticolus ohscurus tends to be larger Fig. 2. — Approximate distribution of tlie races of Sorex vagrans, S. monti- colus, and S. pacificus (modified from Findley, 1955a). The range of S. monti- colus ohscurus is stippled darkly; tliose of other monticolus subspecies, and of pacificus are lightly stippled. (The boundary between ohscurus and coastal subspecies in Canada and Alaska is based in part on vegetation patterns and is somewhat speculative. ) The range of S. vagrans is cross-hatched. Ranges of S. V. vagrans and S. m. ohscurus are considered in more detail in Fig. 3 (in- set area ) . OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY pad REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 7 than S. V. vagrans, but the overlap is so broad that the 110 mm separation point is unworkal)le. Heptner and Dolgov (1967) and Yudin (1969), described the medial tines on the first upper incisors of the Asian shrew Sorex mirabilis, and of S. v. vagrans from Montana. Sorex pacificus, with which mirabilis had been synonymized (Brobinskii et ah, 1944), appears typically to lack this stiiicture ( Heptner and Dolgov, 1967; Hoffmann, 1971; see Fig. 5C). Sorex vagrans and S. nionficolus can be distinguished easily by differences in the position of the medial tines and their relationship to the red pigment on the first upper incisors ( Fig. 5A, B ) . In vagrans the tines are typically small, and located near the upper limit of the pigment; they usually are set off distinctly by a break in the color. In monticolus the tines are typi- cally large, and situated well below the top of the pigment, which is darker and more extensive than that of vagrans. In live-trapping S. V. vagrans and S. monticolus setosus in British Columbia, Myrnal Hawes has noticed that the teeth of monticolus are more robust, harder and more brittle than those of vagrans. Thus, they appear to wear more slowly but break more easily than do those of vagrans (pers. comm.). These differences in tooth pattern remain unchanged with age, although they may be obscured in old shrews as the teeth break and the pigment wears away ( Fig. 5A, B ) . The two patterns do not grade into each other. Measurements with optical micrometer of tine-pigment relationships in 83 S. v. vagrans and 57 S. monticolus obscurus from two homogeneous allopatric populations showed no overlap (Hennings, 1970). We have distinguished vagrans and monticolus with a hand lens while live-trapping in Montana, al- though the technique is difficult to apply to old adults. Mymal and Dave Hawes (pers. comm.) have had similar success in British Columbia, with a population that Cowan and Guiguet (1956:52) thought "demonstrates complete intergradation between S. m. setosus . . . and S. v. vagrans. suggesting conspecificity." Sorex monticolus generally is larger than S. vagrans, even in western Montana where size differences between the subspecies S. V. vagrans and S. m. obscurus are slight.

However, differences in some skull proportions are conspicuous. The skull of S. m. obscurus is significantly broader through the orbits than that of S. v. vagrans (Fig. 6B), and the palate is significantly longer (Fig. 6C). A tri- variate analysis, plotting the three proportions as percentages of their total, shows virtually no overlap between the two species (Fig. 7B). Systematic Accounts The following synonymies include only those references relevant to the scope of this report. Fonnal treatment centers on the two most widely distributed taxa in the Sorex vagrans complex, S. v. vagrans and S. monticolus obscurus, which were studied intensively in western Montana.

This is also true of the one specimen of S. v. paludivagus examined. This deviation occurs sporadically in other populations, and will be discussed below. The geographically iso- lated subspecies, S. v. orizabae, has a typical vagrans pattern; al- though Findley (1955a) felt it was little differentiated from S. mon- ticolus, Jackson (192S) correctly allied it with Sorex vagrans. Among populations of S. vagrans vagrans, total length is quite variable, ranging from 86 mm to at least 120 mm, with means gen- erally from 98-108 mm. (compared with means of 100-112 mm in S. monticolns obscurus. Condylobasal length varies similarly, rang- ing from 15.5 to 17.5 mm in the populations examined, with means 16.2-16.9 ( Hennings, 1970). Larger skulls are found among mon- tane populations. Least interorbital breadth provides a real measure of distinction between S. v. vagrans and S. m. obscurus. Although it ranges from 2.7 to 3.5 mm, the least interorbital breadth of at least 80 percent of all specimens of vagrans is below 3.2 mm; in contrast, about the same percentage of obscurus have least interorbital breadths greater than 3.2 mm. (See Fig. 6B; estimate based on over- lap of standard deviations.) Palatal length in S. v. vagrans ranges from 6.1 to 7.3 mm, but is less than 7.0 mm in at least 80 percent of the specimens; S. m. obscurus is generally greater than 7.0 mm (Fig. 6C). See Findley ( 1955a) for size and color variation in other subspecies. Remarks. — Findley (1955a) was the first to recognize that the small shrew of the northern intermountain region, S. v. vagrans, was not the same as Sorex "vagrans" nionticola from Arizona. He also united the several populations which Jackson (1928) had treated as subspecies with vagrans. West of the Cascades, south along the Pacific Coast, and into the Sierra Nevada and Great Basin, S. V. vagrans is found in a variety of habitats. On the Columbia Plateau it occupies riparian habitats within grassland, sagebiTish prairie and ponderosa pine forest. Where it enters the mountains in northern Nevada, Oregon, ^Vashington, Idaho, and western Mon- tana and Wyoming, the subspecies is usually found in forests of Douglas fir, lodgepole pine, western larch, grand fir, western hem- lock, and red cedar, at elevations below 5,000 ft. Sorex monticolus obscurus, S. c. cinereus, S. palustris navigator, and Microsorex hoiji toashingtoni may live in geographic sympatry in this area. Sorex V. vagrans from steppe and arid forest in Washington, Oregon, and Idaho are smaller than the typical fonii from the Washington coast (Fig. 4). The so-called "Oregon dwarf shrew," S. trigonirostris, is a small S. v. vagrans. Comparison of the t\'pe, and a near-topotype on which Jackson ( 1928 ) based the name, with series of vagrans to the east and west, as well as other specimens from Jackson County indicates that although the type specimen is at the lower end of the size range for S. v. vagrans (condylobasal 12 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY length, 15.6 mm), other specimens from the area show nonnal size variation. Characteristics of the incisors, unicuspids, and foramen magnum position also agree with those of S. vagrans, and distin- guish " trigonhostris" from the ornatus group, in which it was placed by Jackson (1928). The largest S. v. vagrans are found in moist grassland and forest in western Montana, where winters in the shrew's microhabitat are less severe than on the more barren Columbia Plateau. Mezhzherin (1964) demonstrated that size variation in shrews does not follow Bergmann's Rule; shrews from colder, more severe, climates are smaller rather than larger than those from regions of milder winters. This appears to be an adaptation to decreased food supply and increased metabolic demands in regions of colder weather. Gebc- zynski (1965) suggested that seasonal size reduction in individual shrews (Dehnel, 1949; Pucek, 1963, 1965) has a similar adaptive function.

The subspecies S. m. ohscurus occupies the interior of western North America from central Alaska south to New Mexico, primarily in the Rocky Mountains. Two geograph- ically isolated subspecies, S. m. neomexicanus and S. m. soperi, are probably derived from these Rocky Mountain populations (Fig. 2). Around the northern and southern edges of the Columbia Plateau S. m. ohscurus grades into S. m. setosus in the Washington Cas- cades and approaches S. m. permiUiensis and S. m. hairdii in west- ern Oregon (Fig. 3). Populations of S. m. ohscurus extend through the mountains of Utah and northern Nevada, to the Sierra Nevada, with an isolated montane race, S. m. parvidens, in southern Cali- fornia (Fig. 2). A series of coastal subspecies, some of which are characterized by a variant tooth pattern, extends northward from Vancouver Island to Alaska - isohitus, mixtus, ccdvertensis, insularis, prevostensis, longicauda, malitiostis, elassodon, aJascensis, and shu- maginensis - the last also extending into interior Alaska (Fig. 2). Sorex monticolus is appropriately named; its habitat is mainly mon- tane, boreal and coastal coniferous forest and alpine barrens. Diagnosis. — Small to medium size shrews of the subgenus Oti- sorex, similar to S. vagrans, but with medial tines on the first upper incisors typically situated well below the top edge of the tooth pig- ment. The tines are larger, the pigment darker, and the incisors more robust than those of vagrans (Fig. 5B). The tooth pattern sometimes approaches that of vagrans among the northwest coastal races ( Fig. 5E ) ; this confusing anomaly is discussed below. The races of Sorex monticolus are exceedingly variable. Clines of increasing and decreasing size, and changes in intensity of pelage pigmentation proceed in many directions, especially among the coastal mountain ranges (Findley, 1955a). S. monticohis ohscurus were as small as 86 mm long, and as large as 128 mm; mean total length varied from 100-112 mm. Condylobasal length ranged from 16.1 to 17.7 mm, averaging 16.7-17.1 mm. Least interorbital breadth averaged about 3.3 mm, ranging from 3.0-3.6 mm among the four populations analyzed statistically. Palatal length ranged from 6.7- 7.7 mm, averaging 7.1-7.3. (See diagnosis of S. v. vagrans for com- parisons; also Fig. 6A-C.) Remarks. — The usual habitat of Sorex monticohis ohscurus on the Columbia Plateau and in the northern Rocky Mountains is high altitude spruce-fir forest and alpine timdra. ( See U.S. National At- las, vegetation map: A. W. Kuchler, ed., 1967.) Sorex monticolus confronts S. vagrans as low as 3,000 ft. in mid-altitude forests of Douglas fir, lodgepole pine, western larch, and grand fir ( Fig. 3 ) . It may descend to pinyon-juniper woodland on the northern end of the Great Basin, but except for the Ruby Range has not been col- lected from the mountains of central Nevada (see Brown, 1971). It occurs along streams and rivers in the high prairie east of the Con- REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 15 tinental Divide (where va^rans does not occur) and on isolated mountain ranges of central Montana and ^^''yoming, whose forests are of the same t\'pe as those of the Rocky Mountains. No monti- colus have been collected from the pine forests of eastern Montana and Wyoming, and western South Dakota. The incisor tine/pigment configurations we discovered in S. monficohis ohsciirus is characteristic also of the subspecies ala- sccnsis, hairdi, inixtus, monticolus, parvidcns, permiUiensis, setosiis, shiimaginensis, and soperi. Except for monticolus, these forms were previously described as sub.species of "Sorex ohscurus." S. m. mon- ticolus was confused by Merriam (1895) and Jackson (1928) with Sorex vagrans from the northern Rockies. As Findley recognized (1955a), populations of S.m. monticolus from New Mexico, Arizona, Chihuahua and Durango appear to represent a southern offshoot of S. m. ohscurus from the central Rockies. Sorex durcingae, which Jackson (1928) viewed as ". . . in many respects similar to S. oh- scurus . . ." is also a synonym of Sorex m. monticohis; its skull and teeth are virtually indistinguishable (see Fig. 5J). It is not assign- able to Sorex saussurei as Findley thought (1955b). The few specimens of the race neomexicanus that we examined showed a somewhat aberrant tooth pattern, the accessory tines be- ing very small to nearly absent; however, the general pattern is that of monticohis rather than vagrons. James Findley (pers. comm.) checked all specimens of neomexicanus at the University of New Mexico and found none in which accessory tines were entirely lacking. Findley's .subspecies longiquus and ohscuroides do not, in our opinion, deserve recognition apart from S. monticohis ohscurus. The three fonns are identical in tooth structiu-e. Findley (1955a: 49) distinguished longiquus from ohscurus mainly because of its small size. However, Figure 4 shows that specimens of S. m. ohscurus from south and west of the Snake River and from central Montana outside the range of longiquus are, on the average, even shorter than the three Findley topotypes of longiquus. This is consistent with Mezhzherin's hypothesis (1964) discussed earlier. On the other hand, cranial measurements of several longiquus in Findley's report (1755a: 64) fell below minimum values we noted in populations of typical ohscurus. Further data are needed, but ^^Sorex vagrans longiquus" probably represents no more than a cluster of ecotypic variants of S. monticolus ohscurus, similar to isolated montane pop- ulations from the northern edge of the Great Basin. Similarly, Findley distinguished "S. vagrans ohscuroides" as smaller, and ". . . separated from the range of ohscurus by the in- tervening smaller subspecies S. v. vagrans." (1955a: 58). However, Sierra Nevada populations of monticolus are no smaller in size than small S. m. ohscurus (see above), and are not as isolated geograph- 16 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY ically as Findley indicated (Fig. 3). Sorex monticolus obscurtis ap- pears to have reached the Sierra Nevada somtime during the Wis- consin glacial period. Martin (1958) noted that during the height of the Wisconsin the southwestern spiiice-fir forest zone was dis- placed downward 4,000-5,000 ft. in southern New Mexico (and probably most of the southwest). Spmce pollens from this period have been found as far south as the Valley of Mexico. During this time monticolus and vagrans probably moved through continuous forest far into Mexico, giving rise to S. m. monticolus in the moun- tains of Chihuahua and Durango. As noted above, S. vagrans orizahae appears to be a relict of similar origin. A similar corridor of boreal forest must have spanned the south- em rim of the Great Basin, allowing monticolus access to the Sierra Nevada from southern Utah; Major and Bamberg (1967) presented Horistic evidence for such a dispersal corridor. Sorex hjelli, a rela- tive of S. cinereus, and subspecies of Eutamias umbrinus and Phe- nacomijs intermeclius, may have reached California by this pathway, and Sorex nanus, in the ornatus group, seems to have moved into the Rocky Mountains from west to east. Findley believed "ohscu- roides" to be an offshoot of S. vagrans vagrans, but eveiy specimen of California S. m. obscurus examined bears the distinctive incisor pattern of Sorex monticolus. Sorex monticolus parvidens, a rare shrew from the San Bernardino Mountains, California, also appears to be an isolated offshoot of S. m. obscurus. It may also occur in the Piute and Tehachapi mountains, between the known range of S. m. parvidens and the southernmost records of S. m. obscurus in the Sierra Nevada (Fig. 3, question marks). The few specimens from these isolated intennediate mountain ranges available to us (USNM 135947-48; 159416-17) appear to be closer to S. monticolus than to S. ornatus, to which they are currently assigned. Additional specimens are needed before a decision can be reached. Populations of Sorex monticolus from southeastern Alaska and coastal British Columbia i.e., calvertensis, elassodon, insularis, iso- Jatus, longicauda, and prevostensis) have a variable incisor pattern which in some specimens is intennediate between those observed for vagrans and monticolus (Fig. 5E). The color is less intense and the tines are somewhat higher on the face of the tooth than in typ- ical monticolus. We have observed somewhat similar patterns in occasional specimens of Sorex vagrans (Fig. 5F), and in the related S. ornatus (Fig. 5H). They may recall a primitive condition from which the distinctive patterns of vagrans, monticolus, cinereus (Fig. 5G), pribilofensis (Fig. 51), and other Otisorex shrews diverged. At present these island races assigned to monticolus probably main- tain a genetic link with interior populations through S. m. longi- cauda, S. m. obscurus, and S. m. setosus (Findley, 1955a). Foster (1965) suggested that ancestors of the insular races may have been REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 17 isolated from the main body of monticohis during the most recent glacial period, on a Queen Charlotte Refugium. The discontinuity in gene flow may have produced or perpetuated the abberant tooth pattern found among Sorex monticohis from this region; in some ways this situation parallels the relationship of Sorex monticohis and S. pacifictis. The vahditij of the name "obscums." — Our decision to recognize "Sorex ohscuriis" as a valid species led to the discoveiy that the names of the two shrews that had been previously considered sub- species of Sorex vagrans (monticohis, dobsoni) had priority over the name obscums. Merriam (1890) named S. monticohis from speci- mens collected in the San Francisco Mts., Arizona, and subse- quently QSQl) described S. dobsoni from Altin-as (^Sawtooth) Lake, Idaho. By 1895 he had come to regard both as subspecies of Sorex vagrans. Jackson (1928) followed Merriam in his definition of S. vagrans monticola, but reduced S. v. dobsoni to the status of a junior synonym of monticola, which he believed to range from northern Mexico to southern British Columbia. However, Findley (1955a), restricted the name S. v. monticola to shrews from Ari- zona, New Mexico, and Chihuahua. He included the northern shrews in the subspecies S. v. vagrans, along with the races of S. v. amoenus and S. v. nevadensis, fomierly recognized by Jackson (1928), and considered that the name dobsoni applied to inter- grades between S. v. vagrans and S. v. obscums in the northern Rockies. We have examined the holotypes of Sorex monticolus and S. dobsoni. They are clearly members of the species "S. obsctirus" (sensu Jackson, 1928). The earliest valid description is that of S. monticohis Merriam, 1890; Sorex dobsoni Merriam, 1891, and S. obscums Merriam, 1895, are junior synonyms of S. monticohis. The name dobsoni has priority over obscums as the name for the Rocky Mountains subspecies of the dusky shrew; i.e. "S. oh- scurus obscurus" (sensu Jackson, 1928). However, we choose to consider dobsoni a nomen obhtum ( cf . Art. 23b, International Code of Zoological nomenclature, 1964: 23). The code provides that a name may be considered "forgotten" if it has remained unused as a senior synonym in the primaiy taxonomic literature for more than fifty years. The name dobsoni has been applied incorrectly to Sorex vagrans since 1895; Jackson (1928) made it a junior synonym. The name Sorex obscurus on the other hand was applied correctly and consistent with its type from 1895 to 1966, when it was made a synonym of Sorex vagrans (Findley, 1955a). It is still widely known and used. Obscurus is no longer a valid species name, but to dis- card it as a name for the subspecies in favor of dobsoni would cause a great deal of unnecessary taxonomic confusion. We therefore em- ploy the name-combination Sorex monticohis obscurus. 18 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY Sorex pacificus Coues, 1877 Pacific Giant Shrew Sorex pacificm Cones, 1877:650.

(New Combination). Sorex vagrans pacificv^ Findley, 1955:34. (New Combination). Sorex vagrans yaquinae Findley, 1955:34. (New Combination). Holotype. — Adult, sex unknown, skin and skull; USNM 3266, from Ft. Umpqua, mouth of Umpqua R., Douglas Co., Oregon. Range. — Three subspecies occupy humid to dry coniferous and mixed evergreen forests in coastal Oregon and California, often to high altitude on the western flanks of the southern Cascades (Fig. 2). Sorex pacificus yaquinae ranges south from about the Siletz and McKenzie Rivers (near Albany and Eugene), where it may hy- bridize with S. monticolus hairdii (and S. m. permiUiensis?), to the Umpqua River on the coast and inland to the Siskiyou Mountains on the California border. Sorex pacificus pacificus is confined more closely to coastal forests, from the mouth of the Umpqua River in Oregon, inland to the western Siskiyous, and south as far as Men- docino, California. Sorex pacificus sonomae continues south in the redwood forests nearly to the Golden Gate. Diagnosis. — Medium to large sized shrews of the subgenus Oti- sorex, more similar to S. monticolus than to S. vagrans. As in vagrans and monticolus the third unicuspid tooth is smaller than the fovnth, and the foramen magnum is situated more or less ventrally (Find- ley, 1955a). Pigment on the first upper incisors is extensive and dark, but there are typically no medial tines (Fig. 5C). Some specimens of S. p. yaquinae, in the zone of contact with S. monti- colus hairdii have tiny tines suggesting the typical monticolus pat- tern (Fig. 5D). Size varies north to south and from the coast inland; the largest pacificus are on the coast in southwest Oregon and northwestern California. For example, three S. p. pacificus from near Gold Beach, Oregon, had total lengths of 155-163 mm, and condylobasal lengths of 22.3-22.8. Eight S. p. pacificus from near Happy Camp, inland from the coast (Siskiyou Co., California), were 134-149 mm long, with condylobasal length 21.2-21.9 mm. Five specimens of S. p. yaquinae from Newport, Oregon (near the type locality), were 128- 141 mm long, with condylobasal length 19.3-20.5; specimens in the zone of contact with S. monticolus hairdii are even smaller. See Findley (1955a) for details of size and color variation. Remarks. — The three subspecies of Sorex pacificus are larger than any of the races of S. monticolus. Nonnally there are no tines REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 19 oil tlie upper incisors, although the pigment is high and very dark (Fig. 5C'). Specimens assigned to S. p. yaqtiinae from Taft and Philomath, Oregon (near localities from which S. monticolus hairdi have been collected) have traces of medial tines which suggest that pacificus may hybridize with Sorex monticolus (Fig. 5D). Incisor structure varies in populations of S. m. ])airdi and S. m. permilliensis which approach yaquinae in central Oregon, but father north (e.g., Astoria, Portland, Tillamook) S. m. hairdi consistently shows large, low tines and heav)' pigment characteristic of S. monticolus. From his studies of the biology of hairdi and yaquinae, Chris Maser (pers. comm.) concurs with Findley (1955a) that the cline in body size between Sorex monticohis and S. pacificus represents genie intro- gression, the nature of which is poorly understood. The ancestors of S. pacificus were probabh' isolated from typical monticohis dur- ing the Wisconsin glaciation, and limited gene flow may have been reestablished with subsequent post-glacial contact. Brown (1970, 1974) has done preliminary work on the chromo- somes of Sorex vagrans, S. monticohis, S. pacificus, S. ornatus, and S. sinuosus from the coastal region of California, Oregon, and Washington. The normal diploid number in all species is 54, with three small pairs of metacentric autosomes. \^ariation occurs in the number of submetacentric and acrocentric autosomes. Sorex orna- tus and S. sinuosus consistently have 18 (9 pairs) of submetacen- trics (47 specimens from nine localities in central California). Sorex vagrans varies, from 6 submetacentrics (3 pairs) in the San Fran- cisco Bay region (3 specimens of S. v. vagrans; 1 of S. v. hahcoetes) to 4 ( 2 pairs ) in northern California and Oregon ( 7 specimens from four localities). Karyotypes from Sorex monticohis and S. pacificus show a north to south decline in numbers of submetacentric auto- somes, this cline paralleling the morphological intergradation de- scribed by Findley (1955a). Sorex monticohis setosus has 4 to 5 submetacentrics (5 specimens from two localities), and S. m. hairdi has 2 or 4 (4 specimens from two localities). S. pacificus yaquinae has 0 or 1 submetacentrics ( 11 specimens from 3 localities) as does S. m. permihensis (6 specimens from 1 locality) and S. p. pacificus appears to have no submetacentrics (but only one specimen was examined ) . More intensive work needs to be done to substantiate these trends, and to detennine the extent of gene exchange between Sorex p. yaijuinae and S. m. hairdi and between hairdi and permiUiensis south of, and setosus north of the Columbia River. If there are no substantial reproductive barriers between the taxa another nomen- clatoral change will be necessary as Sorer pacificus Coues, 1877, has priority over S. monticohis Merriam, 1890. For the present the evi- dence is not sufficient to justify further revision. 20 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY % PALATAL LENGTH Fig. 7 — (A.)

The two specimens darkly circled have "hybrid" skull char- acteristics. Both are from areas of parapatry or sympatry, the vagrans from Camas Cr., Glacier National Park, Mont., and the obscurus from Three-Mile Cr., Sapphire Range, Ravalli Co., Mont. Discussion Although Sorex vap,rans and Sorex monticolus are sympatric over major portions of their ranges, close study reveals that they tend to occupy different microhabitats, and only rarely are they col- lected at the same trap site. In western Montana S. v. vagrans is largely a shrew of riparian habitat, ranging widely along water- courses throughout the intemiountain region. Its ability to survive at REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 21 high altitudes, on dn- soils, and in boreal forests, appears limited. In Montana the Continental Divide may limit the eastward ex- pansion of its range. Sorex monticoJus ohscurus ranges more widely through montane forests, is less dependent on water, and is found at high altitudes and on dry acidic soils. Where vagrans and monti- colus occur together in the lowlands of western Montana (3,000- 5,000 ft.), we found monticoJtis much less common than vagrans. In British Columbia, Hawes (1975) reported biological and eco- logical differences, including odor (Hawes, 1976), between S. v. vagrans and S. m. setostis which are consistent with our observa- tions, as has Terry (1974) in western Washington. Of all the shrews examined from western Montana, only one or two specimens has the blend of vagrans and ohscurus characters one would expect of a hybrid (see Fig. 7B). Hybridization per se is not uncommon in mammals (Mayr, 1963); it does not follow that hybrids are fertile, or that backcrossing into the parent populations is also occurring. We see no morphological evidence in Montana of broad intergradation cited by Findley when he synonymized Sorex ohscurus (^=monticohrs) with S. vagrans. Moreover, S. v. vagrans differs from S. monticolus and S. pacificus in that the two largest metacentric pairs of chromosomes are subequal in size in the latter whereas in vagrans one is considerably larger than the other; neither is the morphology of the submetacentric chromosomes completely comparable (Brown, 1974). Findley also inferred that intergradation between vagrans and monticohis occurred along the Wasatch Front in Utah and the Don- ner Pass region in the Sierra Nevada of California. Almost all of the specimens we examined from these areas are clearly either S. vagrans or S. monticolus, even when the two occur at the same localities. However, a few "hybrid" tooth patterns (Fig. 5F) were found in specimens from Nevada Co. (Boca Springs; Donner; In- dependence Lake), and Plumas Co. (Spring Garden Ranch, Grizzly Mts.) in central California, while in Utah, possible hybrids were found in Davis Co. (Clearfield), Salt Lake Co. (Parley's Canyon, 5000'; Spring Run, 4400'), and Weber Co. (2 mi. W. ^Roy P. O.; Snow Basin). We also identified possible hybrid specimens from Anthony, Oregon, and southeast of Pocatello, Idaho. In California Sorex monticohis is limited to the continuously mountainous central and southern Sierra Nevada. Of all the po- tential "hybrid" individuals, a single specimen ( from Spring Garden Ranch, Plumas Co., California) more closely resembles monticohis than vagrans in the shape and placement of the accessoiy tines, and is so assigned. This place is separated from montane habitats around Mt. Lassen and Mt. Shasta by deep canyons and broad stretches of lowland forest. Nonetheless, a few shrews from the lowlands between Mt. Shasta and Mt. Lassen (Shasta Co.: Cassel; 22 OCCASIONAL PAPERS MUSEUM OF NATURAL HISTORY Siskiyou Co.: Medicine Lake, and Wagon Camp), where vagrans is common but no monticoJus have been collected, also have incisors conforming to the "hybrid" pattern (Fig. 5F), and Jackson (1928) thought that ohscurus (^monticolus) inhabited the northern Sierra Nevada. (His northernmost record, at McCloud River, Siskiyou Co., was a misidentified Sorex troivhridgu. ) The "hybrid" pattern, wherever it occurs, is reminiscent of mon- ticohis only because the tines are larger and the pigment higher than is characteristic for ?)Orex vagrcins. But the pattern is in other ways essentially vagrans (compare Figs. 5A1 and F); the shape and placement of tines in monticohis is markedly different (see Fig. 5B1). We conclude that the hybrid patterns are actually character convergence - the product of genetic drift or selective factors oper- ating within local populations of Sorex vagrans. The available evi- dence demonstrates no intergradation between vagrans and mon- ticohis. Rudd ( 1955b ) documented a range of gradation in color and morphology of salt marsh shrews in the northern part of San Fran- cisco Bay, which he believed to represent introgression between Sorex vagrans and S. [ornatus] sinuosus. However, Brown (1970) examined the karyot)^pes of these shrews and found that all 13 in- dividuals of the so-called hybrid population at Tolay Creek were karyotypically S. sinuosus (see above) as were 10 shrews from the vicinity of Petaluma Creek which Rudd had regarded as S. v. vagrans. Character convergence in this case, too, must be accounted for by something other than genie introgression. Pizzimenti (1976) discovered a similar situation among prairie dogs (Cynomys). Findley (1955a) regarded shrews of the S. ornatus group (orna- tus, nanus, tenellus, etc.), S. longirostris and S. veraepacis as closely related to the vagrans group, from which they diverged during the late Pleistocene. Presently, S. ornatus is sympatric with S. vagrans only in the area around San Francisco and Monterey bays, and with S. monticohis only in the San Bernardino Mountains; its incisor tine pattern ( Fig. 5H ) is closer to that of monticohis than vagrans, as is that of S. nanus, which is broadly sympatric with S. monticohis in the central and southern Rocky Mountains. In contrast, S. longi- rostris of the southeastern United Stated, regarded by Findley as "close in many ways to S. nanus ^ ( 1955a: 28), has incisor tines which resemble those of S. vagrans; its distribution is wholly allopatric and disjunct from its above-mentioned relatives. These new data mandate re-interpretation of the biogeography and evolution of the vagrans-ornattis-longirostris-veraepacis groups, but will require still fuller understanding of the relationships within and between these groups. REVIEW OF THE TAXONOMY OF SOREX VAGRANS SPECIES 23 Summary Morpliological similarities between Sorex vagrans vagrans and S. monticolus (=obscurus) ohscurus were re-examined. Findley (1955a) interpreted convergence in size and color as evidence of introgression, and redefined the species Sorex vagrans to include also S. ohscurus, S. pacificus, and S. yaquinae (sensu Jackson, 1928). In this paper we describe differences in tooth morphology and cranial proportions, which demonstrate more clearly than past criteria the integrity of S. vagrans and S. monticolus, and to a cer- tain extent, that of S. pacificus. The name Sorex monticolus Mer- riam, 1890, takes priorit)^ over S. ohscurus Merriam, 1895. The latter is conserved as a subspecies name; Sorex dohsoni Merriam, 1891, is considered a nomen oblitum. Sorex vagrans and S. monticohis are biologically and ecologically distinct, although their ranges overlap extensively. There is no evi- dence that character convergence in some localities represents genie introgression, although occasional hybrids may occur. Secondary introgression may occur between Sorex monticolus and S. pacificus, but they should be recognized as distinct species until further research clarifies their relationship to each other.
