Stat. 274. 5°28'.2S., I34°53'.9E. near Aru Islands. 57 meters. Sand and stonc. 

 Stat. 305. Mid channel, Solor Strait, orï Kampong Menanga. 113 meters. Stony.

Colony flabellate and reticulate, 8 cm. in height and 9.5 cm. in spread. The anastomoses 

 are rather extensive in places. The branch origins are from 3 mm. to 8 mm. apart. The calyces 

 are distributed on all sides of the colony, hut are more numerous on the lateral sides, where 

 they are quite closely approximated, being but .5 mm. apart, on an average. The branches 

 terminate in a group of calyces neither one of which seems strictly terminal. 



The individual calyces are cylindrical in form and are set at a right angle to the branches. 

 They are 1 mm. in height and 1 mm. broad, on the average. The calyx walls are filled with 

 triradiate and multiradiate Stachelplatten, presenting the cobble-stone effect described in the 

 discussion of the preceding species, the "stones" being angular instead of rounded. There is 

 some appearance of imbrication in the calyx spicules, the foliaceous expansions of Stachelplatten 

 overlapping so that their exposed edges project upward and outward. The operculum is high, 

 although in the retraction of the polyp its periphery is stinken below the level of the margin, 

 the summit of the opercular cone being considerably above the margin. The opercular spicules 

 are arranged as in others of the genus, there being three spicules forming an acute-angled 

 triangle on the surface of each tentacle. The collaret is well marked, but concealed by the 

 retraction of the polyps. 



Spicules. These are much as in Villogorgia rubra, but the predominating form is a 

 butterfly-shape in which the fore wings are represented by two spindle-shaped processes arising 

 from a common base from which the much smaller hind wings also arise. These latter are often 

 foliaceous expansions approaching Acamptogorgia type. There are also many triradiate forms, 

 crosses, stars, etc. All of the spicules are small. 



Color. The colony is light brown, with a very slight suggestion of a pinkish cast. The 

 spicules are white, or rather, colorless. 



General distribution. The type of this species was from Bass's Strait. 



The Challenger secured it between the Fiji Islands and the New Hebrides at a depth 

 of 145 fathoms. Hiles reports it from Sandal Bay, 30 to 40 fathoms. 



5. Villogorgia serrata new species. (Plate XIII, figs. 3, 3^; Plate XXI, fig. 14). 



Stat. 274. 5°28'.2S., I34°53'.9E. near Aru Islands. 57 meters. 



Colony strictly flabellate and reticulate in form 9.4 cm. in height and with a spread of 

 10 cm. The branches anastomose rather extensively. The distance between branch origins varies 

 from 2 to 8 mm., the average being about 4 mm. The various branches are of about the same 

 diameter (1.5 mm.) throughout. The calyces are thickly and evenly distributed on all sides of 

 the branches, their walls being usually contiguous.
