The larger specimen from Stat. 89 has 22 arms 80 mm. long; the smaller, which is 

 undergoing adolescent autotomy, has 2 1 arms. 



The example from Stat. 96 is quite typical ; there are 16 arms, and in addition a IIBr 

 series ending in a pair of pinnules; the arms are 65 mm. long; the centrodorsal is thin dis- 

 coidal, the dorsal pole flat, 3.0 mm. in diameter; the cirri are slender, XXI, 17 — 18, 9 mm. 

 to 11 mm. long; the seventh or, more rarely the eighth, is a transition segment. 



The specimen from Saleyer is typical with 20 arms 90 mm. long. 



Palaeocomatella A. H. Clark. 

 A. H. Clark. Proc. Biol. Soc. Washington, vol. 25, 1912, p. 18. 



Genotype. — Actinometra difficilis P. H. Carpenter, 1888. 



Diagnosis. — Post-radial structure as in the species of Neocomatella ; proximal cirrus 

 segments, except the basal, elongated ; outer cirrus segments short and hearing dorsal tuber- 

 cles as in Comatella ; centrodorsal large, circular, thin discoidal, the cirrus sockets in one and 

 a partial second marginal row, but the second row, instead of alternating irregularly with the 

 first as in all the other genera of the Comasteridae, is exactly beneath the first so that the 

 cirrus sockets are arranged in columns, five to each radial area.
