380 Miscellaneous. I have also lately taken alive, attached to a piece of Eschara foliacea by a byss^is, a fine specimen of Galcomma Tu7-toni. Mr. Coode has also dredged a specimen of Tri Ionia (^. Ilombergii). The following were my rough notes on its appearance : — " Tritonia (! Ilombergii). A specimen 4 inches in length, taken by jNIr. Coode and Mr. Stanley in fifteen fathoms water, off Lulworth. Colour marble-brown. Head-veil at times bilobed, at other times entire. The margin of veil not fimbriated, but closely set with ten-tacular points. Branchiai in about a dozen tufts on each side of the back. Dorsal tentacles issuing from sheaths having their edges jagged. It appears to me to be intermediate between T. Ilombergii and T. plebeiaJ' I am. Gentlemen, yours obediently, William Thompson. Description of a second sj^ecies of the genus Procnias. By Philip Lutley Sclater, M.A. I have seen several examples of Procnias in collections from New Grenada, and have never doubted their being different from the Bra-zilian species. But ])eing aware that a second member of the genus had been described by Dr. Cabanis in the Musevim Ileineanum under the appellation Procnias Heinei, I applied that name to these birds without much inquiry. Having lately, however, had the oppor-tunity of examining the beautiful collection which contains the type of Dr. Cabanis' description, I find tliat I was in error in so doing. The specimen there designated Procnias Heinei is a female or young male of Calliste atricapilla, Lafr., and belongs therefore, according to my ideas, to a different family of birds. I therefore propose the name Procnias occidentalis for this new species, which may be distinguished from the older one by its smaller size, the less amount of 1)lack on the throat, and by the white belly not extending nearly so high towards the breast. Procnias occidentalis, Sclater. P.
