 Terehratida subquadrata, Jeff., Proc. Zool Soc, p. 402, 



pi. xxii. fig. 4, 1878. 

 *Tercbratida uva, Brod., Proc. Zool. Soc, p. 142, pi. 22, 



fig. 2, 1833. Varies a good deal. 



*Terehratula wyvUlii, Dav., Proc. Eoy. Soc, vol xxvii. 

 p. 436, 1878. A very remarkable, widely-spread, and 

 abundant deep-sea species. 



^ Tere'bratula{Vj dalli, Dav., Proc. Eoy. Soc, vol. xxvLi. 

 p. 437, 1878. One only specimen known, with Ioojd 

 broken, but it belongs to either Terehratida or to the 

 sub-genus Terehratidina. 

 0) Terebratula malvinm, D'Orb., Voy. Am6r. mer6., vol v. 

 p. 674, pi. 85, figs. 27-29, 1847. I have never been 

 able to obtain a sight of this small and very uncertain 

 species. It is not to be found in the Jardiii des 

 Plantes collection, where it was sought for by Prof. 

 Perrier. It is very uncertain whether it belongs to the 

 genus Terehratula. 



West of Kerguelen Island. 



Setubal, Coast of Portugal 

 (Kent, 1870). 



Gulf of Tchuantepec, Guate- 

 mala, 10-12 fms. (Brod.); 

 Twofold Bay ; off Buenos 

 Ay res ; off Heard Island. 



Near South Australia; off 

 Falkland Islands ; off Val- 

 paraiso, &c. (see description 

 of species). 



Off Yeddo, Japan. 



Falkland Islands (?), (lies Utx- 

 louines, D'Orb.) 



Sub-genus Terehratidina, D'Orbigny. 



Loops short and simple, attached to the hinge plate ; in the adult condition rendered 



annular by the union of the oral processes. 



* Terehratidina mjvillii, Dav., Proc. Eoy. Soc, vol. 

 xxvii. p. 436, 1878. The largest and finest species of 

 the sub-genus hitherto discovered either in the recent 

 or fossil condition. Two specimens known. 



*Terehratulina cancellata, Koch., in Kiister's Conchyl. 

 Cab., vol. vi. p. 36, pi. 2^ figs. 11-13. A well-marked 

 species. 

 Terehratidina radiata, Eeeve, Conch. Icon., pi. iii. fig. 

 7, 1871. This seems to be a good species; dejath wanted. 

 Terehratidina (Agidhasia) davidsoni, King, Annals and 

 Mag. of Nat. Hist., 4th ser., vol. vii. p. Ill, pi. xi. figs. 

 1-8, 1871. This species, according to Dr Gwyn 

 Jeffreys and Mr Dall should be referred to Terehratu- 

 lina. It has the loop of Terehratidina, but its beak 

 is very large and remarkable. 



Terehratidina caput-serjientis, Lin., Anomia ca.pid-seiyentis 

 Lin. Syst. Nat., ed. xii. \7 Ql = Terehratidina cornea, 

 D'Orb. =puhensis, Lin. = Terehratidina aurita, Flem.

 attached to coral, and not 

 far from the coast.
