180 Mr. J. G. Jeffreys on the Marine Testacea 



and margaritacea, Ph.). — A. Patelliformis, B. M. (A. scabrella and 

 elegans. Ph.). 



Acephala Palliobranchiata, or Brachiopods. 



Terebratula caput-serpentis. Villa Franca. 



Argiope (Orthis) truncata, Ph. — A. (Orthis) Neapolitana, Scacchi 

 (Orthis seminulum. Ph., Megathyris cistellula, Searles Wood). A 

 careful comparison of Mediterranean specimens with those from 

 Zetland of this variable species, confirms my former opinion of its 

 identity with the Argiope (Megathyris) cistellula of the 'British 

 Mollusca.' It would be desirable if Philippi's name of seminulum 

 could be retained, instead of the prior but less appropriate name 

 given by Scacchi. 



Pteropoda. 



Hyalsea vaginella. Ph. 



Spirialis Australia, Eydoux & Souleyet. — S. Trochiformis, Eyd. & 

 Soul. (S. Flemingii, B. M.).—S. rostralis, Eyd. & Soul. (S. Mac- 

 andrei, B. M.). — S. Jeffreysii, B. M. Spezia, where only a single 

 specimen, however, occurred to me. 



Heteropoda. 

 Carinaria Mediterranea. Nice. 



Gasteropoda Prosobranchiata. 



Chiton fascicularis. Ph. ^ B. M. — C. Siculus, Ph. — C. Cajetanus, 

 Ph.—C. variegatus, Ph.—C. Hanleyi, B. M.—C. Pohi, Ph. 



Patella scutellaris, Ph.—V. fragihs, PA.— P. Tarentina, Ph. (P. 

 athletica, B. M.). — P. Lusitanica, Ph. I did not meet with any of 

 the usual forms of P. vulgata ; and Philippi only mentions it doubt- 

 fully as fossil. It is however a very variable species, and may be 

 identical with P. cserulea of Lamarck (not of Linnaeus), or some other 

 of the allied species which are described by Philippi. 



Acmsea virginea, B. M. (Patella Gussonii, Ph.) 



Dentalium dentalis, Ph. ; and var. semicostata. — D. novemcos- 

 tatum, Payr. (D. dentalis, var. /3, Ph.). Specimens of the last, which 

 I took at Spezia, have ten ribs and no intermediate smaller ones, but 

 numerous fine longitudinal striae. The extremity or apex in my 

 largest specimen is truncated, but apparently not by an accidental 

 fracture. Colour the same as in D. dentalis, but the size is larger. 



Pileopsis Hungaricus, B. M. (P. ungarica. Ph.). 



Gadinia Garnoti, Ph. 



Calyptrsea Sinensis, B. M. (C. vulgaris. Ph.) ; var. gibba ; and 

 var. fulva. 



Crepidula unguiformis. Ph. 



Fissurella Grseca, Ph. Not the F. Grsecaof most British authors, 

 which is F. reticulata of B. M. — F. costaria. Ph. — F. gibba. Ph. 



Emarginula elongata. Ph. — E. cancellata, Ph.
