摘　　要：2019年7月6日,本文作者在云南省红河州屏边县采集到1条雌性冈氏竹叶青蛇,腹部明显膨大,疑似孕蛇,带回实验室饲养。该孕蛇体全长75 cm,体重184 g。2019年7月28日,该孕蛇产出10条仔蛇,其中1条产出时已死亡。孕蛇产后体重104 g。活体初生仔蛇体重5.6~7.8 g,体长18~25 cm;仔蛇出生后1 d内全部完成第一次蜕皮;饲养1个月后鉴定仔蛇性别,其中3条雄性,6条雌性。鉴于有些学者反对使用“卵胎生”一词,本文作者建议将爬行动物“直接生产幼体”的繁殖方式表述为“产仔繁殖”方式,以区别于爬行动物的“卵生繁殖”方式和哺乳动物真正的“胎生繁殖”方式。On July 6,2019,the authors collected a female Trimeresurus gumprechti in Pingbian County,Honghe Prefecture,Yunnan Province.Its abdomen was obviously swollen,and it was suspected of being a"pregnant mother".It was brought back to the laboratory for breeding.The total length of the pregnant mother was 75 cm and the weight was 184 g.On July 28,2019,the pregnant mother gave birth to 10 neonates,one of which died.The postpartum weight of the female was 104 g.The neonates weighed 5.6-7.8 g with the length from18 cm to 25 cm.Within 1 day after the birth,all the neonates finished their first desquamation.There are 3 males and 6 females.In view of the fact that some scholars oppose the use of the term"ovoviviparity",we suggest that the reproduction mode of reptiles"directly give birth neonates"should be expressed as"neonate birth reproduction",which is distinguished from the"oviparity"mode of reptiles and the true"viviparity"mode of mammals.
