The morphology of a copepodid found on Huso huso near the delta of the Volga is described and illustrated. The copepodid bears general resemblance to those of Caligidae but differs from them in absence of the frontal filament and in possession of a primitive first maxilla. It is concluded that the copepodid belongs to Dichelesthium oblongum and that Dichelesthiidae might be more closely related to Caligidae than has hitherto been suspected.
描述并图示了在伏尔加河三角洲附近的欧洲鳇上发现的桡足幼体的形态。该桡足幼体与锚头鳋科的桡足幼体总体相似，但在无额丝和具有原始第一小颚方面与它们不同。得出的结论是，该桡足幼体属于长形双螯鱼虱，并且双螯鱼虱科可能比迄今所怀疑的与锚头鳋科的关系更为密切。
