Ultimate joint of mandibular palp four-fifths as long as the width of the first joint. 5. Anterior prominence of merus of second maxillipede slightly less than one-third the total length of the joint. 6. Chela of second pereiopod slightly shorter than carpus. 7. Merus of third pereiopod very evidently shorter than carpus. 8. Thelycum as in text figure : its principal features being a single large plate, almost round, between the fifth pairof pereiopods. and a pair of triangular plates furnishedwith a few stiff setae at the base of the fourth Ann dope/in? us valens (J)t Tlielycum. The branchial formula is the same as in A. elegany. Thecolouring is also much the same as in that species; the deepblue pigment has almost exactly the -ame distribution,1 butthe black spot on the dorsal aspect of the eyestalk behind thecornea is almost obsolete. 1 Neither this specimen nor numerous examples of .1. cleqann(examined when freshly caught) showed such large areas of dark bluepigment on the abdomen as are depicted by Bouvier for valena (1908,PI. I, fig. 3); otherwise this coloured illustration gives an excellent ideaof the appearance of Irish specimens of this genus. I. 08. 20 Of the six species of Amalopenaeus and Gennadas knownfrom Atlantic waters, this specimen undoubtedly stands nearestto vol ens. It differs, however, from Bouviers account andfigures of that species (1908) in respect of numbers 5 and 8 ofthe characters mentioned above. The second maxilla is alsodifferent, and appears to resemble t
