SURVEY OF THE GENERA AND SPECIES, HITHERTO KNOWN, 
BELONGING TO THE DENDROCHIROTHl. 
Family HI. Dendeochirota:. 
Tentacles dendriform. Retractor muscles present. Mouth and anus at opposite 
poles of the body. 
Subfamily 1. Stichopoda. 
Ambulacral appendages in the shape of pedicels alone, or pedicels together with 
papillae, the latter often placed on larger or smaller processes; they are mostly 
arranged in rows, on the dorsal as well as the ventral ambulacra ; interambu-

Genus 1. Cueumaria, Blainville, 1834. 
Tentacles ten, rarely of equal size, two ventral commonly smaller. Ambulacral 
appendages almost without exception in the shape of pedicels forming one, two, 
or more rows along each ambulacrum. Seldom pedicels also on the interambu- 
lacra. Deposits highly variable, very seldom in the shape of reticulate scales. 
A. Ambulacral Appendages — Pedicels alone. 
I. Pedicels present only on the ambulacra. 
1. Pedicels, at least the ventral ones, arranged in more than tivo rows on each 
amhidacrum. 
Cueumaria godeffroyi. Semper, 1868. 
Body acutely ovate. Pedicels in three to four rows in each ambulacrum, excepting at 
the extremities of the body, where only two rows are present. Deposits — iire-
