描述了产于不列颠哥伦比亚省及邻近沃茨的两个新种--斧螺科（Axinellidae）蠕海绵亚科（Demospongiae）Auletta krauteri sp. n.和Dragmacidon kishinensis sp. n.它们代表了这两个属的范围扩展。两者都是相当常见的，Auletta krauteri潜水深度（87至至少300米）和Dragmacidon kishinensis在浅水（潮间带至30米）。我们提出了一个修正的属诊断Auletta占物种之间的变化，在主要骨针，形成上升的道是oxeas，风格或圆线虫，而不仅仅是oxeas。
Abstract Two new species of Demospongiae are described for British Columbia and adjacent waters in the family Axinellidae, Auletta krautteri sp. n. and Dragmacidon kishinensis sp. n. They represent range extensions for both of these genera. Both are fairly commonly encountered, Auletta krautteri below diving depths (87 to at least 300 m) and Dragmacidon kishinensis in shallow water (intertidal to 30 m). We propose an amended genus diagnosis for Auletta to account for the variability among species in principal spicules that form the ascending tracts to be either oxeas, styles or strongyles rather than just oxeas.
