Alhatroiis expedition, 1902: 



Pailolo cliiiniiel, between Molokai and Maui islands, Station ^ISSfi; depth, 127 

 fathoms; iwttoni, tine sand, yellow mud; t(>mp(M-ature, <)<).5 F. ; 2 specimens, young. 



Northeast and north coast of Maui Island, Station 4079; depth, 143-178 fathoms; 

 bottom, gray .sand, foraminifera; temperature, 60.8^ F. ; 1 specimen. Station 4080; 

 depth, 178-202 fathoms; bottom, gray sand, foraminifera; tt'mpcratui-e, 56.4 F. ; 

 8 specimens. Station 4(>S1: depth, 202-220 faliioms; bottom, gray .sand, forami- 

 nifera; temperature, 51.7' F. ; 5 specimens. 



Vicinity of Kauai Island, Station 4132: depth, 257-312; bottom, fine gray sand, 

 mud; temperature. 46.8 F. ; 4 specimens. 



No station number; 2 specimens. 



Besides the above listed specimens there are two broken and subse([uently 

 mended; these are abnormal. Of the 18 specimens, concerning which the data 

 on the surrounding physical conditions are explicit, 13 were obtained between 178 

 and 220 fathoms, on a gray sandy $oraminiferal bottom, at a tempiMature between 

 50"- and 60^ F.; 4 came from deeper water, 257-H12 fatiioms, tlie temi)erature being 

 lower, 46.8'^ F. The lai'gest specimen obtained came from this greatest depth and 

 lowest tempeniture.

Onginal description. — Studer's descriptinn. published in 1878, is as follows: 



Coralliiiu strongly cotnpres.sed, very wide and narrow, with a thin, cylindrical pedicel, which 

 probably was attaihed, broken below. The wall is smooth, with only concentric lines of growth, the 

 lateral angles ronndiMl, only in the lower third obtusely keeled. The calicular margin strongly 

 conve.x, the difference between the planes of the two axes 16 mm. Six cycles, three of which are 

 equal, therefore aiijjarently 24 systems. Septa smooth, sharp with perpendicular margins. Altitude of 

 the corallnm, l!(t mm.; greater diameter, .56 mm.; smaller, 15 nnn.; angleof divergence of sides, 112°. 



The specimen on which the following table is based is associated with Studer's 

 latum.. It differs in having more widely diverging latertil edges: it is not so much 

 compressed, ami there are almost four cycles of principal .septa. This specimen 

 stands rather between hitnm and typical ji<t nniiiiuin. .^[U'cimen No. 23 of Table II 

 shows .some charactcn-s of latum. The variations are such that 1 do not believe it 

 possible to retain hitmn as a distinct sp;'cies.
