REPORT ON THE RADIOLARIA. 1057 



Subgenus 2. Corythospyris, Haeckel, 1881, Prodromus, p. 443. 

 Definition. Feet branched or forked. 



3. Elaphospyris damaecornis, n. sp. (PI. 84, fig. 10). 



Shell flat and broad, nearly triangular, with slight sagittal stricture and irregular roundish 

 pores ; two very large pores on the frontal and on the occipital face, opposite on both edges of 

 the broad sagittal ring. Basal plate with four large central and several smaller lateral pores. 

 Three horns about half as long as the shell, with two to six irregular branches. Four feet 

 of equal size, about as long as the shell, divergent, forked, with four to six irregular terminal 

 branches. (The shell in fig. 10 is seen from the apical side.) 



Dimensions. Shell - 09 long, 013 broad ; horns 0'05 long, feet 01 long. 



Habitat. Indian Ocean, Cocos Islands, Eabbe, surface. 



4. Elaphospyris cervicornis, n. sp. (PI. 86, fig. 13). 



Shell polyhedral, spiny, with deep sagittal stricture and a small number of large roundish 

 pores ; two pairs of large pores on each side of the ring. Basal plate with four pores. Three 

 large horns as long as the shell arise from the apex between smaller conical spines ; the middle odd 

 horn simple, the two lateral each with a pair of branches. Two pectoral feet very large, divergent, 

 with broad and irregular distal ramification, twice as long as the shell and as the two tergal feet, 

 which are less branched. (Fig. 13 exhibits the shell from the dorsal side.) 



Dimensions. Shell 0'09 long, Oil broad ; horns and smaller feet 0'07 to 0'09 long ; pectoral 

 feet 016 long. 



Habitat. Central Pacific, Station 271, depth 2425 fathoms. 



5. Elaphospyris alcicornis, n. sp. (PI. 86, fig. 12). 



Shell nut-shaped, spiny, with sharp sagittal stricture and large roundish pentagonally framed 

 pores ; three pairs of larger pores on each side of the ring. Basal plate with four larger and four 

 alternate smaller pores. There arise from the apex, between smaller spines, three large, divergent, 

 pyramidal horns, which are nearly as long as the shell, and connected by an arched frontal bridge. 

 Two pectoral feet very large, divergent, prismatic, longer than the shell, and at the distal end with 

 a bunch of thick spines. Two tergal feet half as long and thick, simple (in the figure hidden 

 behind the large pectoral feet). 



Dimensions. Shell 0'09 long, Oil broad ; horns and smaller feet 0'06 long, pectoral feet 

 012 long. 



Habitat. Central Pacific, Station 266, depth 2750 fathoms.
