Astrochele, gen. nov. 
Disk covered with small scales, above and below. Radial 
ribs well-developed. Genital openings small, oblique, close to 
base of arms, at each end of a depression in edge of disk. Teeth 
and tooth-papillz spiniform, mouth papille irregular, small or 
rudimentary, few or solitary. Arm-spines thorny and claw- 
like. Arms annulated, granulated, long, slender undivided. 
Astrochele Lymani, sp. nov. 
Disk strongly five-lobed, the interbrachial spaces, in the dried 
specimen, much incurved. Radial ribs extending to near the 
center, highest and rather angular at the outer end. Whole 
surface of disk, including ribs, closely covered with small, con- 
vex, rounded, warty scales, with a somewhat larger central 
scale, surrounded by a circle of similar ones near the inner ends 
of the ribs and a few others irregularly placed between the ribs. 
On the ribs some of the scales are conical. Under surface, 
except jaws, covered with small round scales or granules con- 
cealing the plates. Teeth slender, acute, rough, in a single row, 
except the under ones (or tooth-papillz), which are in pairs, but 
of same shape. On the side of jaws, near the tip, there 1s a 
very small acute conical mouth papilla, and sometimes another, 
still smaller, near the middle; a similar one is seen lower down 
on the lateral face of some of the jaws. Arms granulated like 
the disk, the annular ridges bearing also a row of small, strongly 
curved, acute, claw-like hooks, which become larger and more 
ark ye toward the tips of the arms, especially beneath. 
oward the base of the arms there are on the prominent, side 
arm-plates, beneath, about three spines having thickened bases 
nd narrowed, acute, thorny, claw-like, brown tips. : 
Diameter of disk, 7™™; length of arms four or five times as 
much. Found clinging to Acanella Normani, from south-eastern 
slope of Le Have Bank, 200 fathoms, Capt. Wm. McDonald, 
(schooner N. H. Phillips). 
HyYDROzOA. 
; Blastothela, gen. nov. 
Hydroid allied to Myriothela and Acaulis. Body elongated, 
sessile, attached at base by slender, simple, root-like processes ; 
a circle of slender tentacles near the base; above these are 
many stout simple processes (blastostyles), which bear the small 
sexual zooids (gonophores) on their sides; upper portion of 
body elongated, covered with small capitate tentacles. 
Acaulhis differs in having no blastostyles, and in the mode of 
attachment; MMyriothela in having branched blastostyles, but 
no basal tentacles. 
Blastothela rosea, sp. nov. : 
Body elongated and rather slender in expansion, with the 
upper portion round and usually nearly cylindrical, obtuse,
