by its tj^pe of spines and its lack of bosses or papillae. It is also 

 more compressed than most of the species of CristeUana with per- 

 ipheral spines. It seems in the mass of material examined to be a 

 very distinctive species.

This beautiful species, allied with C. calcar, has been found to be a 

 common one, both in the China Sea and in the more protected waters 

 of the Archipelago. It has not been noted in the deeper waters of 

 the southern area in which the Albatross dredged — Flores Sea, Gulf 

 of Boni, etc. It apparently is most at home in warm waters of 

 moderate depth. Brady records it from the Philippines in 95 fathoms 

 (174 meters), one of the two stations from which the Challenger 

 obtained it. Some of the localities at which the Albatross obtained 

 the species are off southern and western Luzon; east and southeastern 

 coasts of Mindoro; off western Bohol; Sogod Bay, southern Leyte; 

 off northwestern Panay; off Marinduque; between Cebu and Bohol; 

 Jolo Sea; eastern Palawan; between Samar and Leyte; north of 

 Tawi Tawi, etc. At numerous stations it is recorded as common or 

 frequent.
