CLARK: THE ECHINODERMS OF PERU. 337 



mens, R = 41 mm. The color in life is recorded as "ziegelroth oder gelbroth." 

 There is no longer any justification for the use of the name Cribrella, but the name 

 hyadesi does not seem to have been used hitherto in combination with the proper 

 generic name, Henricia. 



Echinaster cribella. 

 C. F. Liitken, 1871. Vid. Med. f. 1871, p. 288. 



This is another of those unsatisfactory species which has not been met with 

 since it was described. The type was not quite 74 mm. in diameter; nothing 

 is said as to its color. It was supposed to have come from Valparaiso. As Echi- 

 naster is a genus characteristic of warm seas, it is quite probable that it occurs on 

 the northern coasts of Peru, but it is hardly to be expected as far south as Val- 

 paraiso ; yet its distribution may be similar to that of Asterina chilensis. 



Echinaster cylindricus. 

 M. Meissner, 1892. Arch. f. Naturg., 58, bd. 1, p. 184. 



This species is based on a single specimen, said to have been taken at Callao, 

 Peru. In this specimen R = 80-90 mm. and also = 7-^r. The color is recorded 

 as "dark blackish brown." 



Stichaster aurantiacus.

This is one of the characteristic starfishes of the Chilean region. It reaches a 

 large size for a Stichaster, full-grown specimens having R = 120 mm. The color 

 in life is orange or red, but preserved specimens are dull yellowish or pale brown. 

 Specimens have been taken as far north as Callao and as far south as Talcahuano. 

 Dr. Coker met with this species on the rocky shores of the Pescadores Islands 

 and at North Chinca Island. Of the former his notes say, "Abundant; red; 

 brittle," and of the latter, " On rocky shores ; color red ; easily broken ; abundant." 



Asterias gelatinosa. 



F. J. F. Meyen, 1834. Reise um die Erde, 1, p. 222. 

 Plate 6, figure 9. 



Although this species has not yet been recorded from north of Iquique, there 

 is good reason to believe it will be found in suitable localities along the southern 

 coast of Peru. It grows to a large size, full-grown specimens having R = 250 

 mm. and breadth of ray = 50 mm. According to Meyen's original description, 

 the upper surface is milky white, with the spines and tubercles bright orange. 

 Preserved specimens give no hint of such coloration, as they are dull brown or 

 various shades.
