1904 E. S. Goodrich in Q. Jrnl. Microsc. Sci. XLVII. 472 In the majority of Teleostean fish the median and paired fins are covered with a smooth scaleless skin, below which lie the dermal fin-rays. For reasons which will appear later, I propose to call these rays the lepidotrichia.
1963 P. H. Greenwood Norman's Hist. Fishes (ed. 2) iii. 29 The outer part of the fin [of sturgeons] is supported not by horny rays but by bony fin rays, actually modified scales, called lepidotrichia.
