clay), partly west of Sukkertoppen, at St. 28, 65 14' N. Lat., 55 42' W. L., 420 fathoms (soft, brown-gray 

 mud with innumerable arenaceous shells of Rhizopoda) ; and from the Manchester Museum our Museum 

 has obtained a gigantic specimen 1 ) taken near the Cape of Good Hope (Lion's Head N. 67, E. 25 

 miles*, I think, ca. 34 S. Lat.) at 131136 fathoms, together with several other specimens of lengths 

 of about 3 feet, and with polyps 30"" long (according to information from Prof. S. Hick son) 2 ). 

 Otherwise the species seems to be a deep-sea form; on the American side it has not been taken at 

 depths under 220 fathoms, but on the other hand at depths up to 1106 fathoms (U. S. Comm. of Fish, 

 and Fisheries Rep. 1883 (1885) p. 510).

Of this species the Ingolf has brought home 43 specimens from four different stations, and 

 about half of them in a well-preserved state. In all chief characters they agree with the description 

 of Kolliker; at the upper end of the peduncle, however, a distinct elliptical swelling is found in most 

 of the specimens. As will be seen from the table below of the proportions of all the specimens, 

 several small ones are included in the number; but they differ so little from the larger ones, that no 

 doubt whatever can arise with regard to the determination of the species3). In a few specimens the 

 circle of tentacles of the polyps is retracted; as a general rule, however, this is not the case, and the 

 polyps and their tentacles are only contracted in different degrees; the proportions given below are 

 of the polyps including the tentacles. Spicules are only found in the end of the peduncle, of a similar 

 size and form as in the preceding species, but in somewhat greater numbers, at all events sometimes. 

 Sexual organs are present, even in small specimens. Large eggs (or larvse?) are often found in the 

 tentacles. 



1) It measures 1350", the peduncle 190""", its enlargement about 30" in diameter. The polyps are coalesced into 

 groups of 58 individuals, and measure 17 25'nm. American specimens grow to a height of 2 feet, and a diameter of ca. 

 2 5 mm (Verrill, U. S. Fish. Comm. p. 510). 



2 ) West of Tristan d'Acunha, at 35 41' S. Lat, 20 55' W. Long., depth 1500 fathoms, the Challenger> obtained an 

 Anthopt. simplex K611. (a damaged specimen of a length of 4001"!'), which resembles A. grandiflorum, but with only two 

 polyps in each row; this specimen is possibly only an A. grandiflorum the development of which has been delayed, and in 

 which the number of polyps for some reason or other has remained small; in other regions, however, the number of polyps 

 may be greater at a far smaller size of the colony, which is proved by the specimens of the Ingolf, especially the smallest 

 of a length of only 122"; therefore I think it rather hazardous to suppose A. simplex and A. grandiflorum to be identical. 



3) I am therefore able to declare with complete certainty that Roule's <tTrichoptilitm* sp. (I.e. p. 307) has nothing 

 to do with the genus Anthoptilum, but is really, as stated on p. 50, Funiculina quadrangularis.
