A New Species

The genus Ameroculodes Bousfield and Chevrier, 1966 is emended to accommodate a new species of oedicerotid amphipod, Ameroculodes miltoni, common to estuarine habitats of the southeastern United States. In this region the new species has been confused with Ameroculodes (=Monocu- lodes) edwardsi (Holmes, 1905) and Deflexilodes (= Monoculodes) intermedius (Shoemaker, 1930), both of which are distinctly larger and endemic to the cold temperate waters of the Northwest Atlantic. Ameroculodes miltoni can be distinguished from A. edwardsi by (1) having the postero-ventral margins of epimeral plates 1-3 rounded, (2) a short, blunt rostrum, (3) uropod 2 with relatively few dorsal spines on the peduncle, (4) and a subovate telson. Deflexilodes intermedius, like A. miltoni, has rounded epimeral plates, but is readily distinguished by the well-developed, elongate dactyls on its 3 rd and 4 th pereopods. Ameroculodes miltoni occurs over a wide range of salinities (<1°/ °° to 35°/ °° ) and is most common in medium to fine sand or sand-silt substrata. It appears to be an important biotic component of northern Gulf of Mexico estuaries.

A New Species

A new ampeliscid species (Amphipoda, Gammaridea) was recovered in high densities from a depth of about 480 m at the Mississippi Canyon (28 32' N, 89 49' W). Ampelisca mississippiana is described and illustrated based on specimens collected from the head of the canyon, where the species formed an ampeliscid mat with average densities of 12,000 ind. m -2 . Ampelisca mississippiana resembles A. pugetica Stimpson, 1864, and A. mexicana Barnard, 1954a, but differs in the shape of the head, absence of corneal lenses, relative lengths of antennae 1 and 2, shape of the segments of pereopods 7, and shape of the carina of the urosome. The new species also resembles Ampelisca uncinata Chevreux, 1887, but differs in the shape of the head, the dorsal carina of pleon segment 4, features of some segments of pereopod 7, the second uropod and the mouthparts.
