Occasional Papers NOTEWORTHY RECORDS OF SMALL MAMMALS IN TEXAS Heather R. Roberts, Ted W. Joliet, Lottie L. Peppers, Jaws C. Cathey, Roslyn Martinez, John A. Peppers, April L. Bates, and Robert D. Bradley Distributional records for 24 species of mammals were obtained during faunal surveys conducted through¬ out Texas. These surveys were conducted in Dickens Co. in 1994, Lubbock Lake Landmark State Historical Park (Lubbock Co,) on 14 April and 7 August 1996, Peach Point and Guadalupe Delta Wildlife Management Areas (Brazoria, Calhoun, and Refugio Cos.) from 16 March to 22 March 1996, and Gus Engeling and Richland Creek Wildlife Management Areas (Ander¬ son, Freestone, and Navarro Cos.) from 4 June to 10 June 1996. An additional county record for Taylor Co. also is included. The records reported herein include one taxon of the Order Didelphimorphia, one of Inscctivora, two of Chiroptcra, one of Xcnarthra, three of Lagomorpha, 13 of Rodentia, and three of Carnivora. These specimens represent county records as interpreted from distribution maps in Schmidly (1983) and Davis and Schmidly (1994). All voucher specimens are de¬ posited in the Museum of Texas Tech University and are identified by the museum catalog number (TTU). Didelphis Virginian a virginian a Kerr, 1792 Virginia Opossum At the Afton locality, an adult female was col¬ lected in cattails and sedges surrounding a 13-acre im¬ poundment. This impoundment was surrounded by a mixed mesquite grassland and farmland. The speci¬ mens collected at the Lubbock Lake Landmark Slate Historical Park were trapped in a small, isolated forest of deciduous trees surrounding a small spring-fed lake. This wooded area was enclosed on all sides by a short- grass prairie. Specimens examined (12).— Dickens Co,, 0.5 mi E Afton, 1, female specimen (TTU 76242), 11 Sep¬ tember 1994; Lubbock Co., Lubbock Lake Landmark State Historical Park, 8, two female specimens (TTU 76158; 76164) and six male specmiens (TTU 76157; 76159-76163), 14 April 1996. Previously collected but imreported records from Lubbock Co. include: Lub¬ bock, 1, female specimen (TTU 12327), 1969; Ransom Canyon, 1, female specimen (TTU 31598), 1977; 2.5 mi NE Lorenzo, 1, female specimen (TTU 60725), 1989. Cryptotis parva parva (Say, 1823) Least Shrew This specimen from the Peach Point Wildlife Man¬ agement Area was collected from an apparent nest and associated run located under a wooden bridge or pier 2 OCCASIONAL PAPERS, MUSEUM OF TEXAS TECH UNIVERSITY piling that probably had been deposited in this mid-grass coastal prairie region during a hurricane or flood. The habitat was a typical mid-grass coastal prairie. Although the individual was a juvenile (eyes opened while in cap¬ tivity), no other individuals were present at the time of capture. This species probably is rare for this area as there arc very few' trees, fallen logs, rocks, or other types of suitable cover. Specimen examined (1).— Brazoria Co., 10 mi E Brazoria, Peach Point Wildlife Management Area, one juvenile specimen of undetermined sex (TTU 71581), 18 March 1996. Lasiurus borealis borealis (Muller, 1776) Eastern Red Bat These specimens from the Richland Creek Wild¬ life Managamcnt Area were captured in a mist net early in the evening (before 2200 hrs) at a small pond of run¬ off water surrounded by forbs and grasses. A small stand of oak trees was approximately 100 m away from this pond and a large, solitary oak tree on the edge of the pond may have served as a roost. Specimens examined (4).— Navarro Co., Richland Creek Wildlife Management Area, 4, three female specimens (TTU 75361; 76112; 76114) and one male specimen (TTU 76113), 9 June 1996. Nycticeius humeralis humeralis (Rafinesque, 1818) Evening Bat This specimen from the Richland Creek Wildlife Management Area was captured in the early evening hours at the same pond reported for Lasiurus borealis. Specimen examined (1).—Navarro Co., Richland Creek Wildlife Management Area, 1, female specimen (TTU 76115), 9 June 1996. Dasypus novemcinctus mexicanus Peters, 1864 Nine-banded Armadillo Although only one specimen was collected at the Peach Point Wildlife Management Area, several indi¬ viduals were seen over a period of three days. This specimen was collected at the interface of a dense for¬ est and the roadside. Hie individual was pregnant and nearing the end of the gestation period as evidenced by four well-developed fetuses. This species appears to be common to abundant in this area. The specimens from the Gus Engeling Wildlife Management Area were collected in a densely vegetated pmc-oak forest. The specimen from the Richland Creek Wildlife Manage¬ ment Area was collected at the edge of a small pond surrounded by a mix of grasses and forbs and small stands of oak trees. Specimens examined (4).— Brazoria Co., 10 mi E Brazoria, Peach Point Wildlife Management Area, 1, female specimen (TTU 71990), 17 March 1996; Anderson Co., Gus Engeling Wildlife Management Area, 2, female specimens (TTU 75423; 75407), 5 and 6 June 1996; Navarro Co., Richland Creek Wildlile Management Area, 1, female specimen (TTU 75360), 9 June 1996. Sylvilagus aquaticus aquations (Bachman, 1837) Swamp Rabbit Two individuals were observed at the Guadalupe Delta Wildlife Management Area; however, only one was collected. Personnel at this wildlife management area stated that S. aquaticus routinely is observed on the property and probably is common. The specimen was collected at night along an open mesquite area in- terspersed with medium-height grasses. Specimen examined (1).— Calhoun Co., 15 mi SW Port Lavaca, Guadalupe Delta Wildlife Manage¬ ment Area, 1, male specimen (TTU 75212), 19 March 1996. ROBERTS ET AL,— SMALL MAMMALS IN TEXAS 3 Sylvilagus auduhonii neotnexicanus Geomys hreviceps Nelson, 1907 Baird, 1855 Desert Cottontail Baird’s Pocket Gopher The specimens happed at the Lubbock Lake Land- mark State Historical Park were collected in the short to medium-height grassland prairie typical of this re¬ gion. Specimens examined (6).— Lubbock Co., Lub¬ bock Lake Landmark State Historical Park, 3, one fe¬ male specimen (TTU 76168) and two male specimens (TTU 76166-76167), 14 April 1996. Previously col¬ lected but unreported records from Lubbock Co. include: 5 mi NE Wolforth, 1, female specimen (TTU 2511), 1966; 1 mi E Lubbock Hwy. 40, 0.5 mi N Lubbock, l, female specimen (TTU 5554), 1967; 12.8 mi E Slaton, 1, male specimen (TTU 5556), 1967. Sylvilagus floridan us alacer (Bangs, 1896) Eastern Cottontail This specimen from the Gus Engeling Wildlife Management Area was collected in a pine-oak forest of moderate understory. Specimen examined (1).— Anderson Co., Gus Engeling Wildlife Management Area, I, male specimen (TTU 75395), 5 June 1996. Chaetodipus hispidus hispidus (Baird, 1858) Hispid Pocket Mouse This specimen was collected in a sparsely veg¬ etated area characterized by sandy soils and fragmented stands of oak forest at the Gus Engeling Wildlife Man¬ agement Area. A vegetated fence row surrounded this site. Specimen examined (1).— Anderson Co., Gus Engeling Wildlife Management Area, 1, male specimen (TTU 75422), 6 June 1996. Geomys breviceps appears to be extremely abun¬ dant at the Peach Point Wildlife Management Area. These gophers are prevalent in areas characterized by well-drained, sandy soils. Specimens examined (2).— Brazoria Co., 10 mi W Brazoria, Peach Point Wildlife Management Area, 2, female specimens (TTU 71891; 75107), 18 March 1996. Baiomys taylori taylori (Thomas, 1887) Northern Pygmy Mouse The specimens from the Guadalupe Delta Wild¬ life Management Area were collected in a coastal, short- grass prairie intermixed with mesquite. This area was bordered on one side by the Victoria Barge Canal and two oilier sides by various canals and creeks. Baiomys is probably more common in the drier, more inland ar¬ eas. The specimens from the Gus Engeling Wildlife Management Area were collected along oak forest/short- grass prairie edges offering substantial cover. Specimens examined (11).— Calhoun Co., 15 mi SW Port Lavaca, Guadalupe Delta Wildlife Manage¬ ment Area, 4, three female specimens (TTU 75109- 75111) and one male specimen (TTU 75190), 21 March 1996; Anderson Co., Gus Engeling Wildlife Manage¬ ment Area, 7, two female specimens (TTU 75379; 75389) and five male specimens (TTU 75382-75385; 75415), 5 and 7 June 1996. Neotoma floridana rubida Bangs, 1898 Eastern Woodrat This specimen was collected in a dense, brushy, riparian habitat interspersed with numerous fallen logs and brush piles at the Peach Point Wildlife Manage¬ ment Area. No other individuals were captured and no 4 OCCASIONAL PAPERS, MUSEUM OF TEXAS TECH UNIVERSITY nests were seen. Area personnel reported frequent en¬ counters with this species in bams and post piles, there¬ fore this species probably is common in this area. Specimen examined (1).— Brazoria Co., 10 mi W Brazoria, Peach Point Wildlife Management Area, 1, female specimen (TTU 71587), 17 March 1996. Neotoma micropus micropus Baird, 1855 Southern Plains Woodrat This specimen from the Guadalupe Delta Wild¬ life Management Area was collected near an outbuild¬ ing and associated wood and post piles.
