1G6 Mr. W. R. Ogllvie-Grant on the Genus Coturnix, 



and three terminal setae. Mandible with second and third 

 joints of the palp remarkable on account of the dense clothing 

 of spined setee on both margins, and especially on the sides, 

 they are of great length on the third joint; simple or plumose 

 set£e are entirely absent *. MaxilUiyeds and cjnathopods 

 remarkably massive and strong, terminating in a strong 

 simple nail, on either side of which are several large spines 

 which are ciliated on one margin. Legs having the 4-articu- 

 lated tarsus strong and much shorter than preceding joint, 

 nail slender. Telson lanceolate, shorter than inner uropods, 

 gradually attenuating to the extremity, which is narrowly 

 truncate, and armed with three pairs of spines, the inner 

 pair small, the intermediate pair very long, the outer pair 

 somewhat larger than the central pair ; sides of telson with 

 twenty spines of equal size, and about equal distances 

 apart, arranged throughout the entire length. Uropods very 

 narrow ; inner pair witii a group of five spines, closely packed, 

 and increasing in length distally, arranged round the curve of 

 the otolithic area ; no spines beyond these. The pleopods of the 

 male are of the general character in the genus; the specialized 

 outer branch of the fourth pair consists of nine joints, and 

 the antepenultimate bears, like the preceding joint, a pair of 

 plumed setffi ; the penultimate is without appendages, the 

 last terminates in a long spine-like seta, which is densely 

 ciliated towards the extremity. Length 15 millim. 



One male and one female specimen were procured by me 

 when in Dr. Jeffreys's yacht ' The Osprey,' at Valentia, 

 Ireland, in 1870. I do not know under what circumstances 

 as to depth tfec. they were obtained, as I had only labelled 

 the bottle which contained them " Valentia, 1870."

XVI. — Notes on the Genus Coturnix. 

 By W. R. Ogilvie-Grant, Natural- History Museum. 



This paper contains a short account of the species comprising 

 this group and a brief synonymy of the several species, 

 giving the various combinations of names (generic and 

 specific) under which each has been described, and references 

 to the principal illustrations, except in the case of Coturnix 



* Spined setae but short are often present, as in M. didelphys, at the 

 extremity only of the distal joint, the other setse being plumed or simple.
