This species 2>i"esents a noteworthy difference from the other known 

 representatives of Endopachys, by having no lateral tubercles, but as these 

 are very variable in the amount of their development in E. maclurii, their 

 absence does not seem of generic value. A thin cross section of E. minutum 

 shows no structural difference from E. machirii. 



Genus DENDROPHYLLIA de Blainville. 



Dendrophyllia striata sp. nov. 



PI. XXII, figs. 19 to 19b. 



Branched or fascicular (the specimen is not sufficient for one to decide), 

 compound, reproduction by lateral budding. In the specimen that I have 

 there is one large corallite, with a circular cross section, and the other coral- 

 lites, five in number, are grouped irregularly near the base. There are 

 distinct costse whose general direction is longitudinal ; they are coarse near 

 the basal portion of the colony, but higher they di\nde into finer costse. 

 The intercostal furrows are perforate. Wall rather dense, but contains small 

 vesicles, and is perforate. Septa thin, weak, in four cycles The fourth 

 cycle fuse at about half the distance from the wall to columella to the sides 

 of the third. Sides granulate. Columella well developed, but very spongy. 

 Greater diameter of largest corallite, 7.6 mm.; lesser diameter of largest 

 corallite, 6.5 mm.; height of specimen, 17.5 mm.

Dendrophyllia lisbonensis sp. nov. 

 PI. XXII, figs. 20 to 20c. 



This species belongs to the second group distinguished by Duncan, 

 \dz, those Dendrophyllise witli the calices forming vertical series. Calices 

 arranged in rather regular vertical rows, and have a tendency to regular
