have distinct external hyaline lamella, which gives endopodites a 

 more flattened appearance. 



3. Leg 5 (fig. 131e) with short, oblong-ovate or rounded exopodite, 

 exactly as long as wide, with 5 marginal setae and spinulose border. 

 Baso-endopodite as in the typical species. 



Remarks. — The two specimens recorded here have so many char- 

 acters in common with L. ifalukensis that I feel obliged to consider 

 them as a variety of that species. The antennular structure, with 

 the knob on segment 1 and the hook on segment 2, is also as it appears 

 in the typical species. The specimens occurred, together with examples 

 of the typical species, in a sand sample taken some 340 feet from the reef 

 margin at Falarik in the Ifaluk Atoll. 



Genus Loureirophonte Jakobi, 1954 



The following two species are known : 



Females Males 



Loureirophonte catharinensis Jakobi, L. catharinensis Jakobi, 1954

 L. paranamsis Jakobi, 1954 



I am inclined to regard this genus with extreme doubt. First of 

 all, I think there is every reason to doubt the setal formulae which 

 Jakobi gives for the two species. A comparison of the setal formulae 

 with the figures shows that some spinules along the external border 

 of the endopodite, particularly in the endopodite of leg 2, have been 

 counted as setae, while there are no internal setae on the 2nd exopodal 

 segment of legs 2 to 4 — a condition which is found only in the "in- 

 ornata" group of Laophonte and in Klieonychocamptus. Both species 

 mentioned above probably are referrable to the "inornata" group of 

 Laophonte. Should it become advisable to give that group a generic 

 standard, the name Loureirophonte could be used, provided the generic 

 diagnosis can be checked and amplified with the use of Jakobi's 

 specimens.
