co)')K Bi'uzelins. Coropliiiini sal)no)iis, which Stinipson took 'not 

 in a very good state of preservation' out of the stoniaeli of a 

 sahijon, had almost better have been left there, instead of being 

 drawn forth to create a very indistinct species." 



Later Delia Valle ('93) in his Naples monograph relegates 

 Stimpson's species to the limbo of imperfectly defined species 

 with the laconic remark regarding the description of C. spinicorne 

 "Cita caratteri communi a tntti i Corophinm." and regarding C. 

 salmonis "Naturalamente, tntto (|Tu\sto non basta a far distingnere 

 a la n. sp. '' 



Later in his monograph of the Ganniiaridea Stebbing ('06) 

 accepts twelve species as valid and in the appendix adds four 

 more species of Coropldum, but places spinicoriic and salmonis 

 among those "rejected" without remark. 



Since these species appear to be distinct from other's of the 

 genus and their types have apparently been lost, and since their 

 published descriptions are most inade(|uate, it has seemed worth 

 while to publish here detailed tigures and descriptions of the two 

 species. The work has been done and the drawings made under 

 the direction of Prof. C. A. Kofoid, to whom I am also indebted 

 for the privilege of studying the material on which it is based, 

 and for the expenditure of nuich time and labor in the prepara- 

 tion of the manuscript. 



Stimpson's ('57) original description of C. spinicorne reads 

 as follows : 



'' Coropliinin spinicorne St. Inferior antennae half as long as 

 the body, without tlagella, and with a large curved, sharp pointed, 

 spine at the inferior extremity of the very thick third article. 

 Superior antennae nearly as long as the inferior ones. Feet with 

 plumose hairs ; those of the first pair with minute subeheliform 

 hands, palms transvei-se, third and fourth articles with long setae 

 along the inferior edge. Feet of the second pair simple, but 

 with the third and fourth articles conjoined latei-ally. as if form- 

 ing a hand: the fourth article being placed infei'iorly and fringed 

 with long hairs. Caudal stylets as in C. lonfjicorne, except that 

 the external ranuis in the second pair is not cultriform. Color, 

 brownish, darkest at the head, with transverse bands of light yel- 

 low corresponding to the articulations. Antennae bi-ownish.
