the upper limit of the corallum wall. There are four complete cycles 

 of septa (forty-eight in all), arranged as follows: Twelve large thick 

 septa, joined to the columella by very thick pali. The width of each 

 palus is equal to the width of its corresponding septum 5 the upper 

 margins of the palus stands about 2 mm. above the upper surface of 

 the columella, and fully 1 ram. above the notch dividing the palus from 

 the septal lamina. The width of the pali is about 3.5 mm. From the 

 upper margin of the septum to the notch between septum and palus is 

 about 4.5 mm., may be slightly greater. The inner ends of the pali are 

 fused solidly around the colamella and to it. On the sejDtal faces are 

 small granulations arranged in curves parallel to the upper septal mar- 

 gins. On the faces of the pali are granulated or serrated crests arranged 

 in curves parallel to the upper juargins of the pali. Between each pair 

 of these larger septa are three smaller (one of the third cycle and two 

 of the fourth). The members of the third cycle are narrow above the 

 level of the upper termination of the columella; below this they widen, 

 but do not seem ever to reach the columella. The members of the fourth 

 cycle are narrow, and thin except where they arch over the walls. The 

 columella is essential, is composed of several pieces, trabeculse, which 

 are firmly soldered one to another and to the inner terminations of the 

 pali by solid basal calcareous deposit. From the upper margins of the 

 septa to the upper termination of the columella is about 6.5 mm. ; that 

 is, the calicular fossa is about (3.5 mm, deep. The greater diameter of 

 the upper termination is 5 mm., the lesser 3.5 mm., above whose level, 

 as may be gathered from what preceded, the j)aliform a regular crown.

A KEW GENUS AND SPECIES OF TUEBINOLID CORAL 



FROM JAPAN. 



The specimen upon which the subsequent descriptions are based was 

 sent to the U. S. National Maseum by Rev. H. Loomis, Yokohama, 

 Japan. Mr.W. H, Dall asked me to determine it, and as it proves to 

 belong to both a new genus and species, the following generic and 

 specific diagnoses have been prepared: 



LEVIPALIFER, new genus. 



Salient generic features. — Simple Turbinolid; corallum very short, 

 inversely conical in shape, almost discoid; no sign of attachment, living 

 free. Wall naked. Septa within the wall possess entire or faintly 

 crenate margins; external to the wall beset with rounded dentations. 

 Costai dentate, the dentations with blunt or rounded ends. Four com- 

 plete cycles of septa; pali are before all septa and have entire margins. 

 Columella essential, trabecular.
