tween Spongodinte, Siphonogorgiare and Alcyoniidfe. In its large spindles it 

 suggests Srferoplii/fiim, but there are distinct polyp-calyces ; in its stem, densely 

 filled with spicules, it suggests some forms of SiphoiKxjnrgm, but it has no trace 

 of a highly developed authocodial armature ; among Spongodina^ (Nephthyidic 

 of Kiikenthal) its nearest ally is perhaps CapneUn, but the state of the canal- 

 walls and their spiculation is quite different. The whole colony is hard and 

 rigid, the interior being packed with long and thick spindles. A short stalk 

 gives off a few almost vertical branches bearing digitiform lobes covered with 

 polyps. There are low, dome-like polyp-calyces, showing in turned tentacles, 

 and an octoradiate aperture. The canal walls are thin and bear large spindles. 

 The superficial co?nenchyma contains abundant small, club-shaped spicules, 

 sometimes approaching the foliated type (as in Capnclh), and a few spindles ; 

 but all these superficial spicules are very small in comparison with the massive 

 spindles in the interior. 



The new genus ParaMeMiion is proposed for a Veretillid, allied to 

 Stiilohelemmn, Kolliker, and Stt/lohe/emmides, Thomson and Henderson. It is 

 quite probable that with the collection of more material, the apartness of these 

 three forms will be lessened, and that some readjustment will be feasible, 

 such as we have proposed in merging Sderobelemnon with Kopho/jelemmm, but 

 in the meantime the form for which we have proposed the new genus Farabe- 

 lemnon seems to us to have a distinctive generic position. It is an elongated 

 (190 mm.) and cylindrical Veretillid, with the rachis longer than the stalk. 

 The autozooids are distributed over the surface, the interstices are covered with 

 siphonozooids leaving no bare streak. The verructe are formed of long spicules 

 in four groups ending in four triangular points. The quadrangular axis has 

 a shallow groove on the para-rachidial surfaces. The spicules are abundant 

 both in the rachis and in the cutis of the stalk, those of the stalk are rough 

 scales, those in the rachis smooth spindles, cylinders and branched forms. 



Some Characteristics of the Collection. 



(a) When we compare this Littoral Collection with that previously describerl 

 from the Deep Sea, we notice at once the large representation of certain genera, 

 such as Dmdronephthiia or Spongodes, Sclerophi/tnm, Siphonogorgk, Melitodes, 

 Pteroeides, and Cavermdaria, and the absence of other genera, such as Chniso- 

 gorgia and Umhellula. Thus the peculiar series of Si/mpodinm species, six of 

 which were described in Part I., finds no representation here, but instead of 

 two species of Dendronephtht/a we have here about sixty. There were six 

 species of Chrysogorgia in the Deep Sea Collection, but there is none here ; ten 

 species of UmhelUda, but none here ; and the comparison might be pursued in 

 detail. We shall give only one other illustration : the Deep Sea Collection
