Description

This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 edition. Excerpt: ...Suruga Bay, on a rich Melacrinus ground near Enoura and of only about 80 fathoms depth, the "Albatross" (Stat. 37ID; May 11, 1900) trawled up a badly macerated specimen which at the time seemed to me to belong to the present subspecies. A specimen from Homba (PI. V., iig. 12) was growing on a loose stone covered all over with remains of Bryozoa, wormtubes, fec. Others from Outside Okinose are attached to black lava, to masses of volcanic detritus or to some shells (in one case to a Balanus and in another to a Brachiopod). SyUu ramosa seems to be a very frequent, if not a constant, companion of the subspecies; at least I have been able to determine the presence of that commensal Annelid in all specimens (seven in number) from Outside Okinose. This lot of Okinose specimens is of further interest in that it comprises a graduated Tlxl'Bgure u series of differently sized in CriUeroawyha meyeii tubaoaa I J. natural size. dividuals of the subspecies, the extremes representing the smallest and the largest I have as yet seen. To mention a few sjxx'imens in particular. The smallest just referred to is the one shown in the accompanying text figure 1, A (S. C. M. No. 478). It is only 42 mm. high, the stalk being nearly as long as the body proper. The latter is 18 mm. broad. The presence of tubercular prominences on this small specimen as also on such gradatioually larger ones as mensure 57 mm., 73 nun., 85 mm., etc. in height, shows that their their formation takes place very early in the life of the individual. Text-fig. 1, i, represents a moderately large specimen with the typically characteristic shape of the subspecies. (From Outside Okinose, S. C. M. No. 482). Total height, 115 mm. Greatest breadth of body, G3 nun. PI. V., fig....show more
