are more narrow, of nearly the same widtli, giving an ev^en appearance 

 to the cavity of the cup ; they project slightly above the wall, about 

 •01 of an inch, in the form of narrow points, alternately larger and 

 smaller; the inner edges are thin, evenly and sharply dentate, the 

 sides strongly granulated, but not crowded together, the spaces be- 

 tween them being equal to their thickness, or even wider. The col- 

 umella is small, consisting of numerous even papillte, graduating into 

 the teeth at the base of the septa. Walls thin, granulated exteriorly, 

 with low, even costaj on the upper part, which mostly disappear 

 toward the base. 



Diameter of cups "10 to "IS of an inch ; depth '00 to "10 ; height of 

 corallites usually about MO to •25, sometimes "40 to '55 of an inch. 



Panama and Pearl Islands on the reefs, at low-water in pools; 

 Zorritos, Peru; Acajutla; Realejo; La Union, San Salvador, com- 

 mon, — F. H. Bradley. 



The following description, found among Mr. Bradley's notes, is 

 believed to apply to this species, for though no numbered specimen 

 was found corresponding to it, there is no other species in the Zorritos 

 collection to which it would apply : " Tentacles 30 or more, in two 

 unequal rows ; those of the outer row deep pink, with whitish tips ; 

 those of the inner row greenish, wdth whitish tips. Those of the 

 outer row are about one-fourth as long as the diameter of the polyp, 

 and twice as long as the inner ones. Disk nearly transparent, green- 

 ish, with eight very deep pink lines radiating from the sides of the 

 elongated mouth." 



Astrangia pulchella Ven-iU, op. cit., p. 33i. 



Coralla encrusting, consisting of patches of small, low, cylindrical 

 corallites, scattered at distances varying from less than their diameter 

 to more than a quarter inch, and connected together by a thin, calca- 

 reous, basal expansion, much like that of the preceding species, but 

 smoother and with only minute granulations Calicles shallow, coni- 

 cal, with a nari'ow centei', their whole inner surface crowdedly papil- 

 lose, the papillae of the columella being confused with the teeth of the 

 septa, and very small. Septa twenty-four, projecting very slightly 

 above the Avail, or not at all, narrow at the top but broad within, all 

 nearly equal, the edges evenly toothed, and the sides very strongly 

 and roughly granulated, so that the granules of adjacent septa often 

 touch, giving them a crowded appearance. Costae scarcely apparent, 

 even at the summit. Diameter of the cups '08 to •! of an inch ; depth 

 •03 ; height "05, sometimes more.
