摘要
卵膜表面具卵膜丝为银鱼的重要特征。本文记述了十三种银鱼卵膜丝在胚极、侧面及对极的形态特征。其中 4种为首次记载;6种有补充修正。同时讨论了前人的工作。初步按卵膜丝结构把卵膜丝形态归纳为密致、稀疏直丝、稀疏弯丝、稀疏角丝和短线辐射五个型。
The present paper deals with the results of a preliminary study onthe disposition of filaments on the egg-membrane of salangid fishes, among thir-teen species, 4 are described for the first time and 6 with supplements or amend-ments. Five types of disposition are recognized, 1. fine and close, as seen in Protosalanx chinensis (Basilewsky) 2. sparse and straight: Hemisalanx prgnathus (Regan) 3. sparse and waved, Neosalanx oligodontis Chen 4. sparse and angulate: Leucosoma chinesensis (Osbeck) 5. short and radiated: Neosalanx taihuensis Chen
