34 SPECIES OF THE SYSTEMA. 
explained in the ‘ Fundamenta Testaceologie’ of Murray, the 
pupil and standard interpreter of the conchological phraseology 
of Linneus: Recurvate elevate, membranaceze, margine ver- 
sus nates spectante.” In further elucidation of his meaning, 
this very species (47 of the ‘ Systema’) is mentioned by him. 
Born, in his attempted identification, has avoided the error as 
to surface, but has not pondered sufficiently over the expressions 
“ Affinis T. virgate sed minus oblonga, alba, immaculata, nee 
radiata,’—“ Anus ovalis, nec solis marginibus inflexis.” Speng- 
ler, with more probability, has suggested the T. polygona 
(Chemn. Conch. Cab. vol vi. fig. 77) as its representative. 
Our author in his lists has indicated his possession of this 
species, and there still remains in his collection a lyrated shell 
(Tellina plicata, Encyclop. Méth. Vers. pl. 287, f. 3), which 
agrees in every particular (the hinge excepted) with the require- 
ments of the description. The lateral teeth, denied to it in 
the diagnosis, are so small that they might easily have been 
overlooked: still the recognition is not perfect; hence the T. 
angulata can only be referred to that rare shell with a note of 
interrogation appended. 
a 
Gellina gart. 
Although both name and locality were taken from Rumphius, 
yet his shell, being smooth, by no means answers to the “ striis 
transversis recurvatis””’ of the description. In this respect the 
figure of Argenville is likewise defective. Both engravings, 
however, are useful, from indicating the general aspect of the 
veritable gari ; the former represents Psammobia serotina, the 
latter Ps. vespertina. From the outline of these figures, and 
the elaborate description of its dentition in the ‘Museum 
Ulrice,’ little doubt can be entertained that this long sought-for 
species was either a Psammobia or a Sanguinolaria. The fol- 
lowing passage in the ‘Museum Ulrice,’ where full details of 
the specific characters are given, may refer perchance to those 
radiating strie of P. Ferroensis which form rhomboids on the 
hinder lateral areas with the ordinary concentric ones: ‘ Striz 
transverse retrorsum subimbricate ; inter has strias alie striz
