134 THE VOYAGE OF H.M.S. CHALLENGES. 



LIST OF ALL THE SPECIES OF MADBEPOEAEIA DREDGED BY H.M.S. CHALLENGER 

 IN DEEP WATER, AND OF A FEW SHALLOW WATER FORMS, TOGETHER 

 WITH DESCEIPTIONS OF THE SPECIES, AND SOME ACCOUNT OF THE 

 ANATOMY OF CERTAIN SPECIES. 



Family Turbinolid.e, M.-Edw. and H. 

 Caryophyllia, Stokes. 



Caryophyllia berteriana, Duchass. 



A single perfect specimen only obtained, and fragments of a second. 

 Station 3. South of the Canary Islands. Lat. 25° 45' N., long. 20° 12' W. 1525 

 fathoms. 



Caryophyllia Icevicostata, n. sp. (PL I. fig. 1, la). 



Corallum conical, attached by a long stout cylindrical pedicle, which enlarges and 

 becomes encrusting at its base. Surface of the wall of the calicle with a polished and 

 brightly glistening appearance. Primary and secondary costas prominent, equally 

 developed, with slightly sinuous edges extending from the exsert septa to the commence- 

 ment of the pedicle. Tertiary and quaternary costse marked only by faint striae. 

 Calicle oval, deep ; septa all exsert, with coarsely granulate surfaces, the primary and 

 secondary especially prominent with rounded upper margins in six systems and four 

 cycles. Pali stout and prominent, slightly sinuous, with their surfaces beset with short 

 conical projections ; twelve in number opposite the tertiary septa only. Columella 

 composed of four spirally-twisted processes. 



Height 3 cm. ; long diameter of calicles 24 mm. ; shorter diameter 18 mm. 



A single specimen only dredged, attached to a dead Stylasterid. 



Station 343, off Ascension Island, 425 fathoms. 



Caryophyllia claims, Scacchi. 



Var. smithi, Duncan (?). 



Station 75. Off Fayal Island, Azores, 450 fathoms. All small dwarfed attached 

 specimens. 



Station 308. Off Tom Bay, Patagonia, 175 fathoms. Attached to Gorgonoid stems. 



Var. borealis, Duncan (?). One small attached specimen. 



Station 192. Off the Ki Islands. Lat. 5° 42' S., long. 132° 25' E. 129 fathoms. 



Var. transversalis, n. var. (PL I. fig. 2, 2a); 



Wall of the calicle marked by a series of transverse, undulating, slightly prominent 

 accretion ridges of epitheca, marking apparently a succession of intervals of rest in 

 the growth of the calicle. Surface of the coral smooth. Costse little marked, being 

 obliterated by the ridges, except towards the pedicle, where they are present as numerous
