James Wood-Mason, P. E. Soc., 1877, pp. xviii. & xxxiii., has announced 
the discovery of stridulating organs in Scorpio afer and its allies. The 
organs consist of a “scraper” situated on the flat outer face of the basal 
joint of the palp-fingers [bulbous portion of digital joint], formed by an 
oval area of stout, conical, sharp, curved spinules, some of which terminate 
in a long, limp hair ; and a “ rasp,” placed on “ the flat, produced, inner 
face of the corresponding joint of the first pair of legs,” and formed 
by a similar area thickly studded with minute, mushroom-beaded 
tubercles.
