Alcock on Aristevs coralinus, A. in ' Challenger' Macrura, 1888, pi. xxxii. fig. 10, cJ, antennal scale. An adult male and an adolescent male with commencing process of the antennal scale, and an adult female, from Station 115, 188 to 220 fathoms. Colour in life deep crimson. Two males and a very fine full-grown female had been taken off Port Blair in 271 fathoms, and a young specimen in the Gulf of Manaar in 597 fathoms. Our specimens of the female agree absolutely with Johnson's admirable description. Adult males present some remarkable sexual differences; not only is their rostrum short and porrect, not extending beyond the apex of the antennulary peduncles, but their antennal scale is prolonged at the apex into a slender cylin- drical fleshy process as long as the scale itself. This process, Fig-. Aristceopsis Echcardsiana, S, X \. which is an extension of the thickening of the tissues seen in Aristceus virilis and others, is longitudinally grooved dor- sally and is of uniform width from near the base to the blunt apex. With growth the rostrum of the female also undergoes considerable reduction in length ; but it always exceeds the antennulary Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original London, Taylor and Francis, Ltd
