 axis. Colonies in texture are rather india- 

 rubber-like. Common. Hastings. 



VALK.ERUDX

Favourite habitat, over-running Corallina 

 afficinalis. Zooecia ovately cylindrical, 

 slightly narrowing towards the aperture. 

 Rather common. Hastings.

PEDICELLINEA 



PEDICELLINIDJE 



107. Pedicell'ma cernua, Pallas. 



Species over-running Corallina officina/is, 

 throwing up short pedicels, each bearing a 

 polypide and a zocecium at the top. The 

 pedicel is spinous, and as in the other 

 members of this genus, flexible, which is 

 demonstrated by the zooid making a motion 

 as of bowing or nodding. In this species 

 the pedicel tapers slightly towards the top, 

 but is not constricted at the apex, as in 

 P. nutans ; and further the zoflid is greatly 

 more protuberant upon the anal than upon 

 the oral side. 



Pedicell'ma cernua var. g/abra, having a 

 smooth pedicel, also occurs at Hastings 

 together with the type. Both are common.

ECHINODERMA 



HOLOTHUROIDEA 



1. Synapta inh<erens, O. F. Mtiller. 

 Specimens wormlike, of a pale flesh 



colour ; about 2 inches in length and 

 inch in diameter. The body has no podia ; 

 the tentacles are twelve in number and bi- 

 laterally lobed. Spicules occur in the form 

 of anchors and perforated plates ; the latter 

 are egg-shaped in outline, and both are devoid 

 of serrations. On some occasions the fisher- 

 men's nets are choked with these creatures. 

 Rare generally. Hastings. 



2. Cucumaria pentactes, Forbes.t 

 Brighton. 



3. Cucumaria /actea, Forbes and Goodsir. 

 Animal about i^ inches in length, of a 



light chocolate-brown colour. Podia alter- 

 nate, in five rows ; discs of suckers, white. 

 There are ten dendriform tentacles which, 

 together with the disc, are of a light buff 

 colour freckled with brown, the tentacles 

 becoming quite pale towards the tips. The 

 spicules are nodulated, perforated plates. A 

 single specimen trawled half a mile from 

 shore. Rare. Hastings. 



4. Thyonefusus, O. F. Mailer. 

 Specimens about 3 inches in length, flesh- 

 coloured to pink ; test rather delicate. The 

 podia are numerous and scattered generally 

 over the body, but in some cases show a 

 tendency to longitudinal arrangement. The 

 tentacles are dendroidal, and ten in number, 

 two of them being smaller than the others 

 and having red cores ; these two tentacles 

 are constantly applied to the mouth. The 

 tentacles and disc are powdered with brown 

 over the pink ground, and the mouth is of a 

 dark brown. The spicules are sub-rectangular 

 tables with two-legged central pieces. From 

 the Diamond Ground ; rare. Hastings. 



5. Thyonefusus(*}, O. F. Mtlller. 

 Specimens white, barely inch in length, 



probably immature. The podia are plenti- 

 ful and scattered, displaying however some 

 longitudinal arrangement. The spicules are 

 perforated tables with two - legged central 

 pieces, the immature ones being somewhat 

 lozenge-shaped, and the mature ones ovate to 

 sub-quadrangular. There is some little varia- 

 tion between the tables of these specimens 

 and those of the last species, but they are 

 probably referable to the same species. As- 

 sociated with scallops. Shoreham. 



6. Phyllophorus drummondl^ Thompson. 

 Specimens white, about 5 inches in length, 



tapering below ; test rather tough. The podia 

 are scattered rather thinly, and occur to some 

 extent along longitudinal lines. Tentacles 

 seventeen in number, dendroidal, alternating 

 in size ; stems of tentacles rather brown, 

 mouth of a dark brown. Spicular tables 

 rather large, circular to sub-quadrangular in 

 outline. From the Diamond Ground ; rare.
