^ This plate, as well as others referred to in d’Orbigny’s Supplement, was 
never published. D’Orbigny refers also to a figure of this species in his 
Paleont. univ. 1847, pi. Ixxx. figs. 1-4; but I have not access to that work. 
^ This is a doubtful species ; it has the aspect rather of a Cirripede than of a 
Ehyncholite. 
^ Excellent figures of this species were published by d’Orbigny in his ‘ Oours 
Elementaire de Paleontologie et de Geologie Stratigraphique,’ vol. i. p. 271 
(1849-1852), and the same figures were afterwards published by H. A. Nichol- 
son in his ‘ Manual of Paleontology,’ 2nd ed. 1879, vol. ii. p. 55, fig. 466 ; and 
again in the 3rd ed. of the same, 1889 (Nicholson and Lydekker), vol. i. p. 828, 
fig. 739. 
^ Rhynchoteuthis DutempM, d’Orb., and E. hasta, R. tuherculatus, R. uni- 
dentatus, Faure-Biguet, are all regarded by Pictet and Campiche (Pal. Suisse, 
ser. iii. pt. ii. 1862, p. 164) as doubtful species, being briefly described by Faure- 
Biguet. MM. Pictet and Campiche state also that the three last-named species 
may perhaps be Jurassic.
