116 THE PLUMULAKIDJE. 



spur-like, with the orifice directed upward and toward the hydrotheca; about two large cauliue 

 ueinatophores to each stem joint. 



Gonosome. Gonangia borne on special appendages springing from the proximal liydrocladial 

 interuode; appendages straight, divided into internodes, each of which bears a neinatophorous 

 brauchlet in the axil of which grows a gonangium. There may be as many as a do/en gonangia 

 borne on a single phylactogonium.

This is the most abundant plumularian in rather deep water off the Florida coast.

CLADOCARPUS SPECIOSUS Verrill. 



(Plate XXVIII, figs. 8-11.) 

 Cladocarpug spcvioiug VERIULL, Am. Journ. Sci. and Arts, April, 18711, XVII, j>. 311. 



Trophosome. Colony (in fragmentary specimen) nnbranclied, attaining a height of about 

 three-fourths of an inch; stem fascicled, the distal portion, however, is simple and divided into 

 regular rather long internodes, each of which has a strong internal septal ridge near each end, 

 and bears a hydrocladium on a strong process from near its middle portion ; hydrocladia rather dis- 

 tant, divided into regular interuodes, each of which has its cavity ornamented by several (about 

 seven) septal ridges, five of which are behind the hydrotheca, and two in the aduate portion of 

 the mesial nematophore. Hydrotheca 1 stout, regularly widening from base to margin ; anterior 

 profile nearly straight, margin with two rounded anterior teeth and four or live shallow teeth or 

 siunatious on each side; intrathecal ridge low, straight, horizontal; supracalycine nematophores 

 with distal portion narrowed; margins crenulated, reaching to the top of the hydrotheca; mesial 

 nematophore spur-like, with the distal end entirely free from the hydrotheca; proximal end aduate 

 and partly divided by two septal ridges; margin creuulated; cauliue nematophores, four to 

 each iuternode, one large one in front at the proximal end of the interuode and three somewhat 

 smaller ones at the base of the hydrocladium. 



Gonosome. Gonaugia not known; phylactogonia branched, arising from the side of the prox- 

 imal hydrotheca, and not morphologically a modified mesial nematophore, the latter being present 

 as shown in the plate. 



Distribution. Banquereau, off Sable Island, Nova Scotia; depth, 200 fathoms. 



This species was described but not figured by Professor Verrill in 1S79. Among the U. S. 

 Fish Commission specimens sent me from Yale by Professor Verrill I find the type of (J. speciosus 

 from which the above description and the figures were obtained. The species evidently belongs 

 to the paraiUsea group with two prominent anterior teeth. It can be told from C. paradisca by- 

 its much stouter hydrotheca' and from C'. yramlis by its lateral marginal teeth and distally con- 

 tracted supracalycine nematophores and the free distal ends of the mesial uematophores. 



Type. In the museum of Yale University. 



CLADOCARPUS POURTALESII Verrill. 



(Plate XXIX, figs. 1, 2.) 

 Cladocarpm pourtalesii VERRILL, Arn. Jour. Sci. and Arts, April, 1879, XVII, p. 309. 



Trophosome. Colony irregularly branched, attaining a height of about 18 inches; stem fascicled, 

 very thick and heavy in old specimens, the anterior tube alone bearing hydrocladia; hydrocladia 

 closely approximated, alternate, divided into regular short internodes, each of which has three or 

 four short septal ridges, one behind the intrathecal ridge, one under the supracalycine nematophores, 

 one between these two, and often a small inconspicuous one reaching obliquely backward and
