Astrangia pulchella Verrill (1866), Proc. Boston Soc. Nat. Hist., vol. 

 10, p. 331 ; (1870), Trans. Conn. Acad. Arts Sci., vol. 1, p. 527. 



Verrill's 1870 description is as follows: 



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

 corallites, scattered at distances varying from less than their diameter to 

 more than a quarter of an inch, and connected together by a thin, cal- 

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

 smoother and with only minute granulations. Calicles shallow, conical, 

 with a narrow center, their whole inner surface crowdedly papillose, 

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

 and very small. Septa twenty-four, projecting very slightly above the 

 wall, 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 gran- 

 ulated, 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 .10 of an inch; depth .03 ; height .05 ; some- 

 times more. 



"Panama and Pearl Islands, with the last, common, — F. H. 

 Bradley." 



Remarks: Septa 24-28 in number, paliform lobes 4-5 per septum. 

 Although this species is indicated in the key as being closely related to 

 A. (Astrangia) pedersenii Verrill, it differs from that species markedly. 

 The septa of A. {Astrangia) pedersenii, though not as differentiated as 

 those of A. {Astrangia) coronadosensis Durham, are nevertheless un- 

 equal in size in comparison with those of A. {Astrangia) pulchella. 

 The shallow fossae and crowded papillose condition of the interior of 

 the calices further differentiates this species from A. {Astrangia) peder- 

 senii.
