 1851. Lepas peciinata Darwin, Monograph on the Cirripedia, Lepadidse, p. 85. 



A common form on "gulf weed." The valves are radially striate or 

 grooved or are often profusely spinose (fig. 4). It can be distinguished 

 from Z. anserifera hj the very narrow area between the occludent 

 border and the ridge from umbo to apex of the scutum. The tergum 

 is notched to receive the apex of the scutum. The smoother forms of 

 the species often have the capitulum conspicuously inflated (figs. 5, 6). 

 Lepas pectinata is pelagic, and chiefly flourishes in warm seas.
