DE. T. DAVIDSON ON EECENT BEACHIOPODA. 33 



Obs. This is the largest species of Tercbratulina with whicli I am acquainted, eitlier iu 

 the recent or fossil condition. 



16. Teeebratulina Crossii, Davidson. (Plate III. iigs. 4-6.) 



Terebrutulina Crossei, Davidson, Journal do Conchyliologie, vol. xx\. ]>. lOH, pi. vii. fig. 1, 1882. 



Shell large, elongated oval, longer than wide ; valves almost equally convex, mesial 

 fold and sinus scarcely indicated ; dorsal valve feebly auriculated ; beak of ventral valve 

 sliglitly incurved, obliquely truncated by a rather large foramen, margined in part by 

 the umbo and by two small lateral deltidial plates ; surface of valves covered with 

 numerous fine radiating strise, at times almost obsolete, and crossed by concentric lines 

 of growth. Colour light yellowish or light salmon. Loop short, not quite a third or 

 fourth of the length of the valve. Length 2 inches 1 line, width 1 inch 8 lines, depth 

 1 inch. 



Ilab. This magnificent species occurs in Sagami Bay, Japan, where it was dredged by 

 Dr. L. Doderlciu. The locality is situated iu the neighbourhood of station No. 232 of the 

 * Challenger' Expedition, only a little nearer the coast, and in about 100 to 250 fathoms. 

 Dr. Doderlein, who kindly lent me the fine series of Brachiopoda procured by himself in 

 tliat locality, tells me that the sea-bottom is covered with mud, stones, and fragments 

 of volcanic origin, with abundant animal life of astonishing variety, and that there is 

 no better locality for dredging-purposes in Japanese waters. 



Obs. I became first acquainted with this fine species in 1882, M. II. Crosse having 

 kindly forwarded a specimen he had received from Japan, which I subsequently described 

 and figured in his valuable ' Journal de Conchyliologie.' Soon after I was able to 

 purchase from Mr. G. B. Sowerby another good specimen of the same shell, and subse- 

 quently two other fine examples were lent to me by Dr. Doderlein. I have given figures 

 of three of the specimens. It does not appear to be a very rare species in the locality 

 where it is found. 



I may also mention that no single locality has hitherto afforded a larger or more varied 

 assemblage of specific forms of Brachiopoda than the waters that surround the Japanese 

 islands, Corea, and the neighbouring coast of China. I have been able from those seas to 

 examine and describe the following species : —
