Clare Island Survey — Marine Enlomostraca. 45 15 



jointed, first joint with one, second with five setae. Second and third feet 

 of the usual type. Fourth feet (PI. II, fig. 11), endopodite two-jointed, 

 first joint without setae, second joint with two terminal and two inner- 

 edge setae. The second inner edge seta has a remarkable expanded 

 base, to the distal side of which is attached a curious glandular or sensory 

 organ which appears to consist of an oval mass of protoplasm without 

 any definite structure or chitinous covering, analogous probably to the 

 " aesthetasks " of the 1st antennae, occurring throughout the order, or 

 the modified setae on the second maxillae of the Scolecithricidae. Fifth 

 feet (PL I, fig. 9) of the same type as in Laophonte elongata and 

 L. typhlops, the second joint being parallel-sided, about five times as long- 

 as broad, with four outer-edge setae, the two most proximal being placed 

 almost alongside each other, one slender terminal seta and one on the 

 inner edge. The short parallel-sided portion of the first joint carries two 

 terminal setae, and there are two setae on the inner margin. 



This species is closely allied to Laophonte elongata, L. typhlops, and 

 L. longiremis, but may be readily distinguished from the first two by 

 its much shorter furcal rami, and from the last by its six-jointed 

 antenna, two-jointed exopodite of the first feet, and different number 

 and arrangement of setae on the fifth feet. In the peculiar structure of 

 the fourth feet it agrees with none of the three. 



Several specimens were taken in Blacksod Bay, 1-3 fms., in 

 September, 1909, and September, 1911. 



*L. littoralis Scott. — Clew Bay, 18 fms., August, 1910, two. Though the 

 habitat, tidal pools and brackish water, recorded by Scott and Sars for 

 this species, differs from that in which specimens were found in Clew 

 Bay, there seem to be no structural grounds for regarding them as 

 distinct. 

 L. curticauda Boeck. — Clifden and Westport Bays (Brady, Mon.). 



*L. congenera Sars. — Ballynakill, 1901, 6-8 fms., one. 



*L. denticornis Scott. — Off Killary Harbour, 25 fms., May, 1909, one. 

 L. longicaudata Boeck. — Off Killary Harbour, 25 fms., May, 1909, one. 



*L. elongata Boeck. — Off Killary Harbour, 25 fms., May, 1909, several. 



*L. bulbifera Norman. — Ballynakill, 1901, in dredged material from 1-2 fms., 

 one ; Blacksod Bay, 4 fms., September, 1910, one. 

 Laophontopsis lamellifera (Claus). — Ballynakill, 1901, 1-2 fms., one. 

 Asellopsis hispida Br. & Bob. — Westport Bay, surface-net, type-specimen 

 (B. & B.). Clew Bay, 15-17 fms., tow-net on dredge, August, 1910, 

 one.
