DR P. P. rAUPwrrn on the siif,m-s of Panama. 19 



2f)l. Eu'inta recta. The type is a very jroofl speries of Lp!o- 

 ttraca ; but I (loiil)t its identity with the Cnnuu;;ian specimen, with 

 which the Miiziitlaii sliell, M. .'*.■)(), was compared. It a.ost resembles 

 the L. /inearin, M. .')."> I, with wldch it agrees in divergence and 

 general siiape ; but that is very nmch snialler, with the upper whorls 

 more tumid. In the Professor's type of L. recta, I searched in vain 

 for traces of the " two brown spots." They were probal)ly thrown 

 hy defective light. Tlie '* two opatjue spiral bands " are simply the 

 effect of the suture, and the previous whorl showing through. For 

 the Mazatlan shell, M. ."(.'(O, I propose the name of L. involuta. 



292. Eulima solitaria. This also is a Leiostraca, not " 1 Sti/- 

 li/er,'^ and accords exactly with the Leiostraca, sp. iiid. a, .M. .5.52, 

 but not with tlie supp(3sed L. solitaria, M. ,5.")!. The latter agrees 

 in shape with the unique Panama shell, whorl for whorl ; but its 

 base and labrum are much more produced anteriorly. For this rea- 

 son, it may be known as L. producta. 



293. Pyramidella, sp. ind. This is probably the Obeliscua de- 

 scribed in Maz. Cat. no. 486. 



294. Pijramidella conica = Obeliscus conicus, C. B. Ad., not 

 M. 486. 



29.T. Nntica chemnifzii'=N. maroccana, M. .570. The Professor 

 first labelled these shells " N. 1 maroccana, Chem.," but crossed it off 

 in pencil. Another tray appeared (without number) labelled " ]uiii- 

 fasciata. Lam." They all belong to the large M est Coast form of 

 maroccana. [N.B. The shells described in P. Z. S. as " var. cali- 

 fornica,'' on the authority of the late Mr. Nuttall, are (with others 

 from the same source) undoul)tedly from the Sandwich Islands. 

 The Pacific specinu-ns (of which I have examined many thousands, 

 brought by Comm. Wilkes's E. E.) present a very different ty])e from 

 those of the west coasts of Africa and America; but are regarded 

 by Mr. Cuming as only a local variety.] 



296. Natica 1 lurida. These shells are simply a pale variety of 

 N. maroccana. 



297. Natica otis, C. B. Ad. (not Brod. & Shy.). These shells 

 appear to be the young of Polinices " salanyonensis," P. 2C8. 



298. Natica 1 salanyonensis. I had no opportunity of comparing 

 this Polinices with the species of liccluz. 



299. Natica sou/eyetiana. The shells closely resemble N. ma- 

 roccana, but with a larger umbilicus. 



300. Natica Ivirginea, C. B. Ad. (not 'Ktc\.^ =■ Polinices uber, 

 M. 576. 



301. Natica, sp. ind. a. There is no ticket answering to this 

 number, which was probably intended for the ^^ maroccana, var. 

 *' unifusciata." 



302. Natica, sp. ind. b. The shells are marked e, and are the 

 young of Polinices uber, P. 300, M. .576.
