部分鲇形目鱼类嗅觉器官的研究

Studies on the Olfactory Organs of Siluriformes Fishes of a Part

解剖观察６科１０属１９种鲇形目鱼类的嗅觉器官，其嗅囊的形态可分为椭圆形，肾形和卵圆形。初级嗅板的形态可分为复板亚型、厚板亚型及薄板亚型。长椭圆形嗅囊中的初级嗅板为复板亚型和厚板亚型；肾型嗅囊含复板、厚板及薄板三种亚型；卵圆形嗅囊仅有厚板一种亚型，可根据嗅轴特点进一步分为扁平下型和凹窝下型。鲇形目鱼类嗅觉器官的差异可作为科属间一个重要的分类依据。

species siluriformes fishes,belonging to 10 genera,6 families,were dissected.According to the differences of their structures,the olfactory organs may be divided into long ellipse、kidney and egg pattern.the long ellipse pattern may be further subdivided into 2 subpatterns:complex (Siluridae) and thick (Clariidae).The kidney pattern all be Bagridae fashes,may also be subdivided into complex ( Pseudobagrus and Pelleobagrus) thick ( Pelteobagrus and Leiocassis) and thin ( Leiocassis、Pseudobagrus and Mystus). The egg pattern includes only thick subpattern,it may further be subdivided into flat (Amblycipitidae and Ictaluridae) and fossa (Sisoridae and Ictaluridae) infrapattern. The difference of olfactong organs of siluriformes may be used one of the important classified foundation.
