Spicule dimensions of Siphonodictyon rodens (Johnson, 1899); from drawing of spicules of holotype

Substrate: Dendrophyllia ramea; Sampled by 'fishermen' and identified by J. Johnson as 'Acca rodens'. All measurements are of mature, fully formed oxeas (from drawing). Small sample size insufficient, does not allow statistical comparison with other samples. Measurements conducted by C. Schönberg on Johnson's Fig. 2. Data are sorted vertically by spicule width.; Johnson, James Y. (1899) Notes on some sponges belonging to the Clionidae obtained at Madeira.

基质（Substrate）：细枝树珊瑚（Dendrophyllia ramea）；样本由“渔民”采集，经J·约翰逊（J. Johnson）鉴定为*Acca rodens*。所有测量对象均为成熟且完全成型的单轴骨针（oxeas），数据源自手绘图纸。本次样本量过小，无法与其他样本开展统计学对比。测量工作由C·舍恩贝格（C. Schönberg）基于约翰逊的图2完成。数据按骨针宽度纵向排序。约翰逊，詹姆斯·Y.（1899）《关于在马德拉群岛采集的穿贝海绵科（Clionidae）若干海绵的笔记》，载《皇家显微学会会刊》9卷：461-463（*S. rodens*相关内容见第162页，图2）。
