Bemarks. — This species is decidedly dillerent in minor characters from Anthemi- 

 phijJlia paii'va Pourtales from the Antillean seas. .1. pacifica has thinner septa, the 

 septal spines are not compressed transversely to the plane of the septal faces, and 

 there is not that compacting- of the columella and inner ends of the septa by second- 

 ary calcareous deposit wliich at least often occurs in A. patera. The number of 

 septa is about the same. Septal grouping is not so distinct in A. patera. The two 

 spt>cies, however, seem to be very closely related. Pourtales's species was dredged 

 ort' Havana in from 250 to 400 fathoms of water. 



'I"he AlhutrciKs obtained five specimens of A. pacifica. There is practically no 

 ditt'erence between the specimen from Station 3856 and the type, except that the 

 former has a diameter of 9.5 mm. and there are two septa of a fifth cycle. The speci- 

 men from Station 3857 was attached to a Glycyinerls {Pectunculus) shell. Its base is 

 not uniformly rounded, there being two constrictions, indicating intermittent growth. 

 The calice of this specimen is 9.5 mm. in diameter and the corallum 6.5 mm. tall.

Brook pointed out in his catalogue of the genus Madrepora" that the Madrepora 

 of authors beginning with Lamarck, 1801, was not originally included by Linnaeus 

 in that genus, but in MUhpora. \\\ the twelfth edition of the Systema Naturae, 

 Linnanis corrected the error of the tenth edition, transferring M'lUepora iiinricata 

 to Madrepora. Lamarck in 1801, when he undertook the first subdivision of the 

 Linmean 3/adrepora, unfortunately selected Madnpora muricata for the type of the 

 genus as restricted by him. Although Brook knew this historv of the u.sage of
