cailletti, Crosse, to be a good species ; and perhaps so likewise is T. 

 unyuiculus of Cooper. T. radiata, Reeve, is certainly so. 



From the Japanese waters Mr. Adams enumerates three or four 

 species which appear to be all varieties or different states of growth of 



Terebratula caput-serpentis, Linn. sp. (Plate XXX. 



figs. 7, 8, 9.) 



Terebratula caput-serpentis, T.japonica, T. cumingiil, A. Adams, 

 Annals & Mag. of Nat. Hist. 3rd ser. vol. xi. p. 98, 1863. 



Mr. L. Reeve observes, in his 'Monograph of recent Brachiopoda,' 

 that " T.japonica is closely allied to T. caput-serpentis, and is with- 

 out doubt its representative in the Corean and Japanese waters ;" 

 and in this view Mr. Jeffreys fully concurs. 



Hab. Mr. A. Adams got : — T. caput-serpentis living at Tsu-Sima 

 from 26 fathoms (sand and shell bottom), at Tsusaki 55 fathoms, 

 Mino-Sima 63 fathoms ; the variety japonica living at Tsusaki 55 

 fathoms, and Gotto, 48 fathoms, and in the Straits of Korea from 63 

 fathoms, and sixteen miles from Mino-Sima, the bottom being coarse 

 black sand and broken shells ; the variety angusta living from 54 

 fathoms off the island of Guelpart, seven miles from the shore, the 

 bottom being black sandy mud. T. caput-serpentis was also dredged 

 by Mr. Adams along with T. coreanica and IF. picta off the Straits 

 of Korea in 46 fathoms, four miles from Tsussima (at Tsu-Sima), 

 from a bottom of sand and broken shells. Mr. Adams's specimens 

 of T. cumingii(1) are evidently young examples of T. caput-serpentis, 

 and were dredged alive at Tsu-Sima, 26 fathoms, and at Mino-Sima 

 in 63 fathoms. 



Genus Waldheimia, King. 



A number of recent species have been proposed, described, and 

 illustrated ; but I think they may be reduced to the following nine, 

 viz. : — W. fiavescens, Val. apud Lamk. ; W. venosa, Sol. ; W. cranium, 

 Mull.; W.grayi,T}ax.; W. picta, Chemn. ; W. lenticularis, Desh. ; 

 W. septigera, Loven; W.jloridana, Pourtales ; and W. raphaelis, 

 Dall., — these three last presenting a good deal of general external 

 resemblance, although said to be specifically distinguishable. 



Waldheimia raphaelis, Dall. (Plate XXXI. fig. 9.) 



Waldheimia raphaelis, Dall, American Journal of Conchology, 

 vol. vi. p. Ul, pi. vii. figs, ad, 1870. 



This species has been described by Mr. Dall, who informs me that 

 he has compared it carefully with authentic examples of W. septigera, 

 Loven, and finds it quite distinct — that it is more than twice as large 

 as the largest W. septigera and of a different colour, the Japanese 

 shell being deep brown, with a slight rufous tinge, while the hinge- 

 plate, septum, ovaria, and muscular impressions present notable dif- 

 ferences in their details. Mr. A. Adams does not appear to have 

 found Mr. Dall's shell or Loven's W. septigera during his Japanese 

 dredgings, and mistook for this last a specimen of Terebratella 

 spitzbergensis.
