6 2 PORIFERA. II. 



seen tliat this latter, if it were drawn in the same way as Carter's figure, would get a quite similar 

 appearance. The other form mentioned in a parenthesis, to which belong the figures 16, g, h, and 19, 

 a, b, I suppose, on the other hand, to be A. infundibulum Levins. Of Armauer Hansen's figures the 

 cited ones may with great probability be referred here. The two varieties enumerated by Levin sen 

 under his c?tpr ess/for mis are certainly two well separated species, and only var. robusta belongs to the 

 present species, while var. lycopodium is a separate species. Of Fristedt's Cladorhiza cupressiformis 

 I have examined a type-specimen; the species is identical with the present one, and when Fristedt 

 says that his species is wanting forcipes, he must have overlooked them, I suppose, on account of 

 their being only found in the upper end; the fact is that they are really found in his specimen. With 

 regard to Lambe's species Esperclla Frist cdtii the facts are rather peculiar; I have examined a frag- 

 ment of one of his specimens. First this fragment proved to have forcipes, which must accordingly 

 have been overlooked by the author; but then this fragment did not belong to this species, but to 

 the following one, and accordingly it evidently belongs to the specimen that Lambe mentions sepa- 

 rately. According to the description and the figures there can now be no doubt that the two other 

 specimens are A. cupressiformis. The spicules mentioned bv Lambe and figured in fig. 2, d and e, also 

 corroborate this view, as they are exactly the embryonal spicules mentioned above under the embryos. 

 When Lambe says that his species deviates from cupressiformis by not having forcipes and by its 

 outer form, the reason of the first fact is that forcipes have been overlooked, and the latter fact cannot 

 well be decided from Carter's diagrammatic figure of the exterior. When he further mentions differ- 

 ences in the form of the chelae this statement is of no consequence, as neither Carter's figures nor 

 those of Lambe himself are correct; Carter's, however, are far the better ones. 



Locality: Ingolf, station 3, between the Faroe Islands and Iceland, 63 35' Lat. N., io° 24' LongW., 

 depth 272 fathoms, and at East-Greenland on the following localities: 72 40' Lat. N., 20 c 00' Long. W., 

 depth 100 fathoms; 72 27' Lat. N., 19° 50' Long. W., depth 120 fathoms; and at the south coast of Jame- 

 son's Laud, depth 10—60 fathoms (The East-Greenland Expedition 1891 — 92); five specimens in all. 



Geogr. distr. The species was taken by the « Porcupine between Scotland and the Faroe Islands, 

 at depths of 384, 363, and 632 fathoms, with the following respective bottom temperatures : -4- o°8, 

 -^o°3, and -=- o°8 C. Then it has been taken in the Kara Sea, depth 51—81 fathoms (Levinsen); west 

 of Taimur, 76 18' Lat. N., 92 20' Long. E., depth 40 fathoms (Fristedt); the Baffin Bay at depths of 200 

 fathoms and 60 — 100 fathoms (Lambe). Thus the species is known from a territory between 70 Long.W. 

 and 92 Long. E., and between ca. 6o° and 76 Lat N., with a bathymetrical range from ca. 40 — 632 fa- 

 thoms. The species seems chiefly to be a native of the cold bottom, as most of the mentioned locali- 

 ties, or perhaps all of them, have a negative bottom temperature. Only the Ingolf-statiou 3 is a sure 

 positive locality with a bottom temperature of o : 5C, but then it is also of some interest to notice the 

 fact that the mentioned deviating leaf-shaped specimen is obtained just on this locality.
