is orbicular, six inches in diameter, and covered with blunt 

 spines, those on the margin being much the largest, and the 

 anterior marginal spines are bifid. The tips of the walking 

 legs are black. Eriphia gonag-ni ( Fabr. ) has a broad, 

 rounded carapace, with an antero-lateral row of sharp, re- 

 curved spines. The hand and carpus are covered with ver}- 

 peculiar, smooth, shining, round nodules arranged in longitu- 

 dinal series. The chela? are brigl^t crimson in color, and the 

 right finger bears a large truncated prominence on the basal 

 part of its cutting edge. One of the most beautiful crusta- 

 ceans in the entire collection is a specimen oi Plagns/a dcp/rssa 

 Say. The carapace is orbicular and covered with nodules 

 interspersed with round, bead-like granules. The anterior 

 part is strangely shaped, having a projecting lip or ridge pas- 

 sing under the eyes and antenna?, and showing deep clefts 

 above for the recesses into which the antenna? are folded. 

 The superior surface of the carapace is mottled with crimson 

 and grayish pink, and that of the chela? and walking legs is 

 marked with broad, longitudinal bands of the same color. 

 The chelee are especially gorgeous in their ornamentation, 

 which consists of rows of nodules and the crimson stripes men- 

 tioned above. The ventral surface is, as usual, without bright 

 markings. Carpilliis coralliuiis (Hbst.) is a very large, 

 bright-red crab, with perfectly smooth, rounded carapace and 

 massive chelse. The fingers are jet black. 



The land-crabs are verv abundant on the island, and appear 

 to belong to three or four species. There is the small and 

 ever present Geocarcinus lateralis (Frem.) .with its bright red 

 and vellow coloring. It was especially abundant in the cave 

 where the •• leaf-nosed " bats were secured. Next we have 

 Cardiosonia <^nanhuiui (Latr. ). the common large edible 

 species of a grayish color, and with no bright markings. In 

 addition to these are what appear to be two other species 

 which the writer secured during his former visit to Eleuthera. 

 Both are about as large as C. giianhiimi. One is of a deep 

 rich wine-color, with two round, light yellow spots near the 

 posterior margin of the carapace. The other is green in color.
