20 SPECIES OF THE SYSTEMA. 
not a Swedish, species, and one, moreover, intended to have 
been named ovatus by Linneus, as we learn from his hand- 
writing attached to Ellis’ drawing ; Leuwenhoek’s engraving is 
irrecognisable; Lister’s (at least in his Anim. Angl.) exhibits 
the ordinary aspect of ovularis. These two last might pass for 
B. rugosus, but that is never littoral. Hence, upon the whole, 
the claims of ovularis to be held the L. balanoides of Linneus 
appear the best grounded. 
It is not unworthy of remark that ‘cum priore” precedes 
“sed” in the original: the passage as printed reads somewhat 
obscure. . 
Heyas tintinniadbulura, 
The figures referred to all exhibit the general aspect of the 
richly painted Balanus, usually designated by this epithet 
(Wood, Gen. Conch. pl. 6, f. 1, 2), but whether all may have 
been designed for the same species is perhaps to be doubted. 
The older representations of the Cirripedes rarely display 
those latent characteristics which modern research insists upon ; 
the opercular valves were generally wanting in the examples 
depicted. ‘There is no reason for doubting the correctness of 
the traditional recognition, although the European locality is 
not strictly a suitable one: living specimens, however, are abun- 
dantly found in almost every port, on the bottoms of merchant- 
men. It is probable, too, that our author confounded it with 
the tulipa of the Mediterranean, of which, as well as of tintin- 
nabulum proper, there is an example in his collection. The 
details of the ‘Museum Ulric’ are very meagre; the trans- 
verse striz of the interstitial areas, there spoken of, are 
frequently absent in mature individuals. 
Lepas Wladeura. 
Gualtier, where cited, has delineated, and Boccon (293, not 
294) described, the Coronula diadema of authors; Rumphius, 
on the contrary, has figured Cor. balenaris, but the description 
in the ‘ Mantissa,’ and even the ‘“‘ subrotunda” of the ‘ Systema,’
