摘　　要：对四川产中菊头蝠喜马拉雅亚种（Rhinolophus affinis himalayanus）和马铁菊头蝠日本亚种（R．ferrumequinum nippon）的23项外部形态指标和22项头骨形态指标进行了测量，并进行数理统计分析。结果表明，（1）中菊头蝠喜马拉雅亚种和马铁菊头蝠日本亚种的23项外部形态测量指标中有2项差异显著（P〈0．05），16项差异极显著（P〈0．01），其中：中菊头蝠喜马拉雅亚种（n=14）体长小于59mm（47．30～58．40），尾长小于26mm（21．69～25．68），耳长小于22mm（18．36～21．88），前臂长小于56mm（50．9～54．20），第Ⅲ掌骨第一指节长小于16mm（13．2～15．53），第Ⅲ掌骨第二指节小于32mm（27．38～31．74）；而马铁菊头蝠日本亚种（n=6）体长大于62mm（62．43～66．76），尾长大于30mm（30．56～36．18），耳长大于24mm（24．47～27．20），前臂长大于56mm（58．78～63．46），第Ⅲ掌骨第一指节大于19mm（19．38-21．39），第Ⅲ掌骨第二指节大于34mm（34．42～38．11），这些差异可作为区分四川产这两个种的依据。（2）中菊头蝠喜马拉雅亚种和马铁菊头蝠日本亚种的22项头骨形态测量指标中，除颅高、听泡间距差异不显著（P〉0．05）外，其他20项指标都存在极显著差异（P〈0．01）。Twenty three measurements of external morphology and 22 measurement of skull morphology on Rhinolophus affinis himalayanu.s and R .ferrurnequinum nippon were taken. Univariate analysis and disefiminant analysis were applied to those measurements. The results of univariate analysis indicated ： （ 1 ） Of the 23 measurement of external morphology on R. affinis himalayanu.s and R. ferrumequinum nippon, 2 showed significant differences （ P 〈 0.05） and 16 showed extreme significant differences （ P 〈 0.01 ）. Length of head and body of R. affinis himalayanus is shorter than 59 mm （47.30- 58.40 mm） （n = 14）, the length of tail is shorter than 26 mm （21.69 - 25.68 mm）, length of ear is shorter than 22 mm （18.36 - 21.88 mm）, length of forearm is shorter than 56 mm （50.9 - 54.20 mm）, length of the first section of Ⅲ metacarpal is less than 16 mm （ 13.2 - 15.53 mm）, length of the second of Ⅲ metacarpal is less than 32 mm （27.38 - 31.74 mm）. However, length of head and body of the R. ferrumequinum nippon is longer than 62 mm （62.43 - 66.76 mm） （ n = 6）, length of tail is longer than 30 mm （30.56 - 36.18 mm）, length of ear is longer than 24 mm （24.47 - 27.20 mm）, length of forearm is longer than 56 mm （58.78 - 63.46 mm）, length of the first section of Ⅲ metacarpal is more than 19 mm （19.38- 21.39 mm）, length of the second section of Ⅲ metacarpal is more than 34 mm （34.42 - 38.11 mm）. These differences between the two species might be regarded as the basis for identified characters. （2） Of 22 measurements of skull morphology, the differences in nasal bone length and greatest breadth of nasal bone between the two species are not significant, and the differences of other measurements are extremely significant（ P 〈 0.01 ）.
