with the deeply serrate margins, impart a particularly ornate 

 appearance. The genera Hebclla, Cry f tularin and Graiinmirin 

 were each represented by new forms. 



The Sertulariu.e was but poorly represented, their being 

 only two species, ScrtularcUa Li;axa l'(/r. robnsta Allman. and 

 6". distans Allman.^ The Pia;mli.arid.-e, however, came up 

 in quantities, and constantly elicted exclamations of surprise 

 and delight at their exquisite grace and beauty. Some were- 

 of monstrous size for this group, reaching a height of two feet 

 or more. Among the more notable prizes were two species 

 of Allman's genus Schizj.'r/c.'ia. a genus nitherto am'epresented 

 in the West Indian region. The name is descriptive of the 

 fact that the pinnae are divided or split into two branches. I 

 am inclined to believe that one of these branches is mereh" a 

 modified ph3'lactogonium, a specialized branch for the pro- 

 tection of the reproductive organs. Two species of Pliiiiiti- 

 laria, P. attcunuata Allman and P. geiiiinata Allman. were 

 collected from rather deep water. The beautiful genus 

 AgJaophenia was represented by three species originally des- 

 cribed by Allman, . I. apocarpa, A. i^racilis and A. r/^'ida. 

 There has been considerable discussion regarding the yalidit\- 

 of the last two species. They were described originalh- with 

 the reproductive portion or gonosome of A. gracilis unknown. 

 Afterward, Dr. J. Walter Fewkes seems to have found the 

 gonosome of the latter, and considered it the same as that of 

 A. rigida, and seemed inclined to regard the two species as 

 identical. Our specimens, how^ever, show the gonosome to 

 be quite. different from that of A. rig'ida, the corbula having 

 about ten pairs of entirely free leaflets with a row of nemato- 

 phores on both sides of each leaflet. The trophosome has been 

 compared with specimens in the Museum of Comparative Zool- 

 ogy at Cambridge identified by Clarke, and thcN- were found 

 to agree. A new species of Ag'Ia ^plicnia secured In' us has a 

 very large and ornate corbula which varies greatly in length 

 in different specimens. The leaflets are numerous, twelve
