Tylototriton asperrimus Unterstein, 1930

A single adult specimen (AMNH 163989/ IEBR 69) was found submerged among the detritus of a 0.5­m­diameter temporary forest pool at 1700 m on Mt. Tay Con Linh II (site 3). Adjacent to the pool, five clutches of larvae in opaque gelatin capsules were found ~ 5 cm underground. The only other Vietnamese record of this species is from the AMPHIBIA: ANURA BOMBINATORIDAE

Bombina microdeladigitora Liu, Hu, and Yang, 1960

An adult male was found in a 12­cmdiameter, mud­filled tree hole at 1900 m on Mt. Tay Con Linh II (site 4). This specimen has melanic spines along its chest, chin, and first three fingers. Recorded from the Hoang Lien Mountains, Lao Cai Province, this is the first Vietnam record of B. microdeladigitora east of the Red River (Ohler et al., 2000; Orlov et al., 2001). It is otherwise known from China: Yunnan and Hubei Provinces (Ohler et al., 2000) .

MEASUREMENTS (in mm, AMNH 163789/ IEBR 58): SVL 61.63, SNT 8.38, HDL 28.41, HDW 23.59, EYE 6.60, IOD 3.85, HND 12.35, TIB 27.74, FTL 35.52.

MICROHYLIDAE

Microhyla sp. Figures 3 , 4

A juvenile specimen (tail just resorbed) of an unidentified Microhyla species was col­ one or two low rounded tubercles on upper eyelid; venter smooth; in preservative dorsum tan with large irregular dark brown medial spot, dark ‘‘V’’ on posterior end; arms banded with two or three transverse bars, legs with two transverse bars; venter dusted brown; chin spotted white, throat dusted darker than chest, belly, and thighs, lightest dusting on medial surface.

This specimen looks superficially like M. ornata , but differs in having snout rounded in profile (obtusely pointed in M. ornata ) and the presence of a median longitudinal groove on the dorsal surface of digits, producing the appearance of two scutes (absent in M. ornata ) (Parker, 1934). We refrain from naming this species because it is only represented by a juvenile specimen.

MEASUREMENTS (in mm, AMNH 163848): SVL 17.40, HDL 7.79, HDW 5.48, SNT 2.72, TIB 10.23, FTL 14.43, HND 5.28, EYE 2.10, IOD 2.04.

163848), juvenile. Scale equals 2.5 mm.

lected in a rice paddy in Tham Ve Village (600 m).

It has the following characters: body slen­ der; head rounded, snout bluntly rounded, projecting in profile; tongue spatulate, not notched; tympanum hidden; no vomerine teeth; finger I less than one­half the length of finger II; tips of fingers II–IV and toes II– V slightly expanded (= base of phalange), dorsal surface of digit­tip disks with circummarginal grooves and faint dorsal median longitudinal grooves producing the appearance of two scutes (as in Bourret, 1942: fig. 9i); tarsus smooth, without folds; foot webbing basal, at level of proximal subarticular tubercle for toes I, II, and preaxial side of III, between first and second subarticular tubercle for toes IV, V, and postaxial side of III; two metatarsal tubercles, inner short and oval, outer tall, projecting; dorsum smooth,
