Excerpt from Proceedings of the California Academy of Sciences, 1982-1984, Vol. 43 Length of specimens is given as standard length unless total length is expressly indicated, and all proportional measurements are given as times in standard length (sl). Vertebral counts were made from radiographs prepared in the Department of Ichthyology, cas. Sections of Skin anterior and ventral to the pectoral fin were removed with a scalpel and stained in alizarin to facilitate illustration of the scales. Orientation of the scales is also obvious in radiographs and can be observed in whole specimens without special preparation.
