i. Peru; Vierau.— Four specimens, all of medium size; one has 

 twenty-one arms; the IIBr series bearing the single (internal) IIIBr 

 series is 2, all the other division series being 4(3 + 4) ; the cirri are 

 IX (with some rudimentary), 16-17; another has twenty arms, with 

 all the division series 4(3 + 4), and cirri VI, 16-17; a third has nine- 

 teen arms ; five of the IIBr series are 4(3 + 4) and three are 2; a single 

 IIIBr series is developed on the inner side of a post-radial series 

 bearing two IIBr 2 series; the fourth specimen is smaller than the 

 others; it has eighteen arms, with eight IIBr 4(3 + 4) series. 



Carpenter and Hartlaub assumed that " Peru," the locality whence 

 these specimens are said to have come, is the country of that name in 

 South America ; but the western coast of both South and North Amer- 

 ica is quite barren of crinoids except in very deep water and in the 

 extreme south and extreme north. I have suggested that the " Teru " 

 meant might be Peru or Francis Island situated in about i° 30' S. lat., 

 176 E. long., in the Gilbert or Kingsmill group. This species is 

 known to occur in these islands. Professor Pfeffer and Dr. Michael- 

 sen tell me that the specimens collected by Vierau form part of a very 

 old collection and that the localities as given are unreliable. 



2. Moreton Bay, Queensland. — Three specimens; two of these 

 have nineteen arms ; the third has twenty-seven arms ; all of the 

 post-radial series but two are regenerating at the synarthry between 

 the elements of the IBr series ; one of the unregenerated post-radial 

 series (the right posterior) has the IBr series 6(5 + 6), this bearing 

 two IIBr 4(3 + 4) series. 



3. Sulu (Jolo) Archipelago. — Two specimens, each with some of 

 the arms greatly lengthened and attenuated.
