Mr. G. A. Smith of the British Museum (Natural History) has sent me a de- 

 scription of the type together with photographs of the skeleton. This species is a 

 typical Calvasierias with thick skin and very large superomarginal plates. The 

 caiinal ridge carries a narrow zone of coarse tubercles (one or two wide) continued 

 as a pentagon on the disk. No others are present. The superomarginals are very 

 broad, with a large beaded area, and are wider than the dorsolateral area. Each 

 inferomarginal carries two short, obtuse, granular spines which are set at an angle 

 of 45° to the wall of the ray. On the dorsal side of their bases these spines have 

 become engulfed in the thick integument.

5. CALVASTERIAS STOLIDOTA Sladen.

Mr. G. A. Smith has sent me a description and photographs of the skeleton of 

 this species which, from Sladen's figures, resembles a Kalyptasterias. The dorso- 

 lateral area is broader and the superomarginals much smaller than in typical Calvas- 

 terias. The abactinal skeleton is well developed with strongly overlapping carinals. 

 The mostly 3-lobed dorsolaterals form an irregular open reticulum, in which three 

 or four meshes can be counted between the carinals and superomarginals. The area 

 is nearly or quite twice as wide as the superomarginal plates, and hence much broader 

 than in antipodum, in which the superomarginals are wider than the dorsolateral area.
