In spite of the fact that, in the last few years, our know- 
ledge of the anatomical features of this group has been greatly 
widened, we still are acquainted with so few genera, that the 
time seems hardly yet ripe for a discussion of those modifica- 
tions, which are likely to be ultimately introduced into the 
systematic classification by further morphological study. For 
the present, therefore, this series of papers! will, it is hoped, be 
continued as simple descriptions of anatomical structure, with- 
out any attempt as yet at such discussion. An account of 
the following species will be found below: 
Duncania barbadensis, p. 405, | Heteropsammia multilobata, 
Madrepora, sp., p. 409. p. 412. 
Galaxea esperi, p. 409. | Bathyactis symmetrica, p. 416. 
DUNCANIA BARBADENSIS (Pourtalés). 
Some sections of a decalcified specimen of this rare coral 
were entrusted to me by Professor Moseley; unfortunately 
the series is incomplete, and this, combined with the fact that 
1 As I have frequent occasion to refer to the earlier papers of the series, 
it will be sufficient to give here the volumes of this Journal in which they 
occur: “ Anat. Madr.,” No. I, in vol. xxv; No. 1, in vol. xxvii; Nos. III 
and LV, in vol. xxviii.
