Sumiiiiirv of tlio results of tlie coiiiparative study: 



The fonillum wall is solid, except in some instances it may be synapticulate 

 at the periphery: because of the habit of the corallum of brcakino- into segments and 

 subse(|uentlv being added to, the easy recognition of the ditierent septal cycles is not 

 expected; but in a specimen like one of those of /-'. pidcheUa^ in which the segments 

 have not as yet become dissociated, the primaries are mon^ pronounced than the 

 secondaries; the septal margins are finely dentate; the septal lamellte show precisely 

 the same variation as in CyrJoxerix, from cribriform to solid. 



The dose relationship between Cycloserix ii sp. Philipp'nux to Dlaseris distorta 

 has been pointed out. Dltixerln sp. Philijiptms may be undescribed, but with no 

 more material for comparison I would not name it. One specimen of DinHirh 

 pnlchelJa Verrill is intensely intei'esting. In handling the specimen a segment was 

 broken out, but the specimen originally was eii'cular. A\'hen it is taken in connection 

 with CyclfiKeris 2 sp. Philippine.?^ strong (>vidence is adduced against Diaseris being 

 generically separal)le from (' i/ch >,'<,_ rix. 



The specimens from the Gulf of California are very similar to Doderlein's 

 Piaseri'f-iorm of Pimgia patella.
