It is possible that the form wliich we have identified with LeptoptUum 

 (jracile, Kdlliker, and referred to Funiculina quadrangularis, Pallas, is really the 

 young stage of this new species of FimiculiiM.

Subfiimily Stachyptilidee. 

 Stachyptilum maculatum, n. sp. Plate VII. figs. 5 and 9 ; Plate IX. fig. 16. 



This species is represented by one complete club-shaped specimen, 62 mm. in 

 height. 



The rachis is club-shaped, gradually increasing in diameter and reaching its 

 maximum a little below the apex. It presents a rather striking appearance owing 

 to the presence of l)rown siphonozooids on the surface not occupied by autozooids. 



The autozooids are arranged in ten oblique rows on each side, each row 

 consisting of 3-4 polyps. They are fairly large, and capable of complete retrac- 

 tion ; they show no spicules in their thin walls. The tentacles are of median 

 length, and gradually taper to the distal end. They have one row of 12-14 

 short blunt pinnules on each side. 



The siphonozooids form slight lirown projections on the surface, and appear 

 as eight-rayed stars. They vary in diameter from 0"2-0'3 mm., and the larger 

 individuals are slightly oval. They cover all the surface of the rachis not occupied 

 by the autozooids, and seem also to occur in two grooves that run up the 

 rachis. These grooves on the rachis may be due to contraction in the preserving 

 fluid. 



The spicules are rod-like, with jagged ends, or four- to five-rayed forms. They 

 vary in length from 0'l-0-16 mm., and in breadth from 0'025-0'04 mm. 



This species differs from those previously described in the greater variety of 

 spicules, in having more of the rachis covered, and in the aljsence of papillfe at the 

 upper end of the stalk. 



Locality : Station 213 ; 21° 25' N., 68° 02' 30" E.; 137-131 fathoms. 



Family ViRdi-LMUD^E {Pavonaridce, Jungersen). 



Pavonaria willemoesii, Kijlliker = Mici'optihim tvillemoesii, KoUiker. 



A broken specimen witli a total length of 116'5 mm., of which the stalk 

 occupies 33 mm., thus leaving a long rachis. Tlie axis is cylindrical, from 0"35- 

 0'4 mm. in diameter. The diameter of the stalk is 0*4-0 '5 mm., and it is 

 cylindrical just below the origin of the rachis. The cieuenchyma is thin, and 

 allows the axis to shine through on the prorachidial surface, but is considerably 

 thicker on the metarachidial surface.
