130 RECENT MADREPORARIA OF THE HAWAIIAN ISLANDS AND LAYSAN. 



43-06 fathoms; temperatniT, 71.7' F.; coarse sand, broken shells, corals; 24 speci- 

 mens, includinj^ Nos. 1-7 of table. 



Vicinity of Kauai Islands, Station 4128; depth, 68-253 fathoms; 2 specimens. No 

 locality, 2 specimens. Total, 4.s specimens. 



Dr. Charles (iravier. of the Museum d'Histoire Naturelle, Paris, has sent to me, 

 in a lot of material submitted for identitication, 12 specimens collected at Djibouti, 

 French Somaliland. east coast of Africa. Thesi^ specimens and those from the 

 Hawaiian Islands are in some instances so similar that if mixed they could not be 

 separated. 



It is doubtful wlictlicr Professor Dcklei-lein's Fiuupa erona" can b(> kept distinct 



from F. patella.

 1893. Diaxcrisfraijilis Alcock, Jour. Asiatic Soc. Bengal, LXII, Pt. 2, No. 2, p. 148, pi. v, fig. 11. 

 Corallum Dlaseris-iovm, very slightly arched adorally, outer edge rather thin, 

 base imperforate, almost flat or slightly concave. Two specimens were obtained, 

 1 consisting of a single segment, the otlicr of two united segments. 

 The measui'ements are: 



"Greatest diameter, :i() mm. 



Costa' low, ci'owded, fine, niiiuitely granulated along their edges, sul)equal or 

 slightly alternating in size. They may be contiiuious from the periplieiy to the apex 

 of the segment or may be contined to a peripheral zone, the inner portion of the base 

 sliowing crowded, irregularly disj)osed small graTiuIations. 



Septa very luimerous, 1S4 in the smaller segment of specimen No. 2; in the larger 

 specimen between 7 and 8 cycles, crowded, varying in tliickness, rather thin in speci- 

 men No. 1, rather thick in specimen No. 2. When the edge of the corallum is looked 

 at in profile, all are of equal prominence, but immediately within they usually alternate 

 in height. The smaller fuse to the sides of the hirger. Those representing the first 

 and second cycles are more pronnn(Mit adorally than the others. The .septal margins 

 ai-e finely dentate, the dentations irregular in size and shape, sometimes two-pointed. 

 The septal faces are bes(>t with very niunerous, very crowded, prominent bliuit 

 granules.
