OF MADEIKA AND NEIGHBOUKING ISLANDS. 279 



on the back the zooecia are marked out by ribbed sculpture, and there is 

 ahnost an entire absence of punctation. A fine specimen measures 20 mm. 

 high and 12 mm. wide. 



Dredged in about 70 fathoms, and I found very fine specimens in the 

 Funchal Museum. 



Idmonea fragilis, Calvet (Exped. Scient. ' Travailleur ' et ' TaHsman,' 

 Bryozoaires, 1906, p. 470, pi. 30. fig, 10), would seem to be this species 

 with the cells longer than usual.

1879. Idmonea concava, Waters, " Bryozoa from Bay of Naples/' Ann. & Mag. Nat, 

 Hist. ser. 5, vol. iii. p. 274. 



Clusters of zoa?cial tubes usually consisting of three ; the clusters are 

 more widely separated from each other than is usual, their lower portion 

 attached to the branch straight ; free portion very little raised and not 

 extending beyond the sides of the branch ; surface with scattered punctures. 

 Back remarkably flat or even slightly concave, sculptured with longitudinal 

 lines and punctate. The examples found agreed with Neapolitan specimens 

 given me by Mr. Waters. Dredged in 50-70 fathoms. 



Idmonea pedata, n. sp. (PI. 33. figs. 6-9.) 



Zoarium small, very rarely branched, usually consisting of a single stout 

 stem 10-12 mm. long, which, when looked at laterally, has a wavy outline, 

 bending down here and there are curious foot-like supports. These pedicels 

 are 2-4 in number to each specimen, and are apparently used for attach- 

 ment to some object, but although I have examined about 200 specimens, I 

 have only found one actually attached ; this example was situated on the 

 Foraminifer Polytrema miniaceum of Pallas. The zooecial clusters contain 

 normally three tubes, which are of moderate length. The under surface is 

 slightly punctated, and sculptured longitudinally and also with transverse 

 curved lines. 



Dredged abundantly in about 70 fathoms to the east of Funchal, off the 

 coast between the Lazaretto and Cabo do Garajao.
