Proctor reported that "One may go to the Narrows [near Bar Harbor] at low tide today and find . . thousands of individuals readily accessible . ." Proctor believed (evidently on the basis of shell color and shape) that L. alveus and T. tes- tudinalis were identical species. Their abundance may have been a source of his confusion. It is possible that he found dislodged L. alveus individuals upon rocks and er- rant T. testudinalis individuals on eelgrass blades. There are reports ofL. alveus from rocks (Stimpson, 1851; Jack- son, 1907; Morse, 1910) that Morse (1910) believed to be the result of specimens detached by waves and storms. Lottia alveus was on occasion also found on other sub- strates. There is, for example, a specimen (MCZ) collected in 1897 at Isle au Haul, Maine, attached to the periwinkle Littorina liltorea (Linnaeus, 1758), bearing the label, "living thus on this specimen of L. lillorea which was on (a) float. . in bed of ; The typically rock-dwell- ing limpet Lottia pelta (Rathke, 1833) can be found oc- casionally in California on the blades of the surfgrass Phyllospadix when dense stands of the latter overlap in- tertidal rocks (, pers. observ.) Reconstruction of the biology o/"Lottia alveus The morphology, anatomy, habitat, and collection rec- ords of Lottia alveus permit a partial reconstruction of the biology and natural history of this extinct Atlantic species. There are no studies of the extant subspecies in the North Pacific Ocean. Abundance As with many now uncommon animals and plants re- ported as "common" or "abundant" in the nineteenth.
