Canaries. A. tenuispinus, M. Tr. : number of arms and madreporic plates (2-4) 
variable ; specimens occur with 1-2 larger and a group of 2-6 arms in course 
of formation; exposed individuals are small, but those in protected localities 
are larger and more regular, e. g. with 7 equal arms and 4 madreporites.

LjUNGstAN ^13) notices 67 species or prominent varieties : — 39 (14 new) 
from West-Indian localities ; 6 (3 new) from the Azores ; 4 (3 new) on the 
Josephina bank (lat. 36° 46' N., long. 14° 9' W. ; 6 (4 new) on or off the 
. coast of Portugal. According to him. the tribe Ophiodermatidce (correspond- 
ing chiefly with Ijutken’s Ophiodermatidce , Ophiochcetida*^ and Opliiolepidce) 
is divided into two subtribes — the Opliiodermatince (Ophiodermn, Ophiopeza, 
Pectinura.) Fbes., Ophiopezella^ g. n., Ophiochceta^ Ophioconisy and Ophiopce- 
pnJe.y g. n.) and the Ophiolepidince {Ilemieuryahy Ophiaraclmclla , g. n., O^dii- 
olepisy Ophiomusuwi, Ophiothyreus, g. n., Ophioglypha, and Ophiocten). Ophi- 
opezUy Pet., = Ojjhiopsammus, Ltk. ; but O. fallax is not Ophiarachna spinosuy 
Ljgm., which is type of Ophiopezella \ Ophiarachnella = Pcctinuraj\^i\i. nee 
Forbes. 
Lyman (16) has examined and identified the originals of most of the Ophiu- 
rides enumerated but not recognizably described by Duchassaing (Anim. Rad. 
d. Ant.); there seems, however, no sufiicient reason to adopt the latter’s names 
in the few cnaes which have priority.

Ophioderma tonganum, sp. n., Liitken (16, p. 76), Tonga Islands (first indi- 
cation of this genus in the Indo-Pacific Ocea ). 
Ophiopcspale differs from the other types of this group, through its long, flex- 
ible arms, few (3) arm-spines, and two oral papilla? below each series of dental 
lamina?, as in Amphiura, and from all hitherto described Ophiuridee through 
the ventral arm-plates being divided into two unequal parts. The very de- 
licate granular investment of the disk covers the radial, oral, and adoral 
shields and the innermost arm-plates. O. gocsiancty sp. n., Anguilla, 180 
fathoms. Ljungman (13, p. 616).
