L. LONGiMANus (G. 0. Sars). (G. 0. Sars, 1900, p. 68, pi. 

 48.) Taken on mud bottoms, in 20 to 70 feet of water. Sta- 

 tions: D32, 46, 48. 



Ekdiastylis Stebbing 



I hold with Stebbing that the species included here are gen- 

 erically distinct from Diasfylis. If this view is not taken, vir- 

 tually the entire family must be placed in one genus. 



E. scuLPTus (G. O.'Sars). (G. 0. Sars, 1871, p. 24, pis. 

 1-9.) This species also is found on muddy bottoms, depth 20 

 to 220 feet. Stations : D 1, 10, 13, 15, 17, 23, 25, 29, 32, 33, 35, 

 46, 47, 53, 55, 59, 61-63, 70, 92, 93, 118 ; P lOB. 



E. coRNUiFER Blake. (Blake, 1929, p. 30, fig. 15; Zimmer, 

 1930, p. 649, fig. 47.) Taken once on a bottom of mud and 

 shells, in 70 feet of water. This species is known to occur 

 from Eastport to Casco Bay. Station : D 70. 



Lampropidae 

 Lamprops G. 0. Sars 



L. QUADRiPLiCATA Smith (fig. 42). (Smith, 1879, p. 118.) 

 The coloration of this species is more striking than is usual 

 in the Cumacea. The carapace shows a dividing line pass- 

 ing diagonally forward from just in front of the postdorsal 

 angle to just behind the anteroventral notch. The area in 

 front of this line is greenish white and behind it deep brown.
