( Fig. 2I )

Pisa mutica Gibbes, 1850: 171 (type locality: Charleston Harbor, South Carolina).

Pelia mutica – Rathbun 1925: 278 ( St Thomas). — Hernández-Ávila et al. 2007: table 1, Cubagua.

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1♀ MNHN-IU-2013-4612 (lot JL373a), st. GR 11, 13 m ; 1♀ ov. MNHN-IU-2013-5663, st. GB 36, 16 m.

DIAGNOSIS. — Greatest width of carapace about two-thirds its greatest length. Outer margins of rostral horns either diverging anteriorly or parallel.

HABITAT. — On rocky subtidal and sessile epifauna; on seagrass Halophila stipulacea . Also found on rubble or shell bottoms and inside large sponges. Collected 13-16 m, reported 1-51 m.

DISTRIBUTION. — Western Atlantic. Massachusetts to west coast of Florida , Cuba, Puerto Rico. Lesser Antilles VI (St Thomas), ICA ( St Martin *, Guadeloupe, Martinique **), IOV ( Margarita , Cubagua ). * St Martin from unpublished fieldwork ( UF32010 , 13.IV.2012; coll. & photo A. Anker / G. Paulay). ** Martinique from unpublished fieldwork (XI/2015, coll. R. Ferry / Y. Buske, det. J. Poupin, specimen in BIOSPHERES, University of Fort de France) .

Pelia rotunda A. Milne-Edwards, 1875 ( Fig. 2J )

Pelia rotunda A. Milne-Edwards, 1875 (1873-1880): 74 (type locality: Desterro, Brazil).

MATERIAL EXAMINED. — Guadeloupe. KARUBENTHOS 2012, 1♀ MNHN-IU-2013-4609 (lot JL1067-4), st. GB 20, 16 m ; 1 ♂ MNHN- IU-2013-4419 (lot JL1499-6), 1 ♀ MNHN-IU-2013-4419 (lot JL1507), 1♀ MNHN-IU-2013-5947 (lot JL1507), st. GB 36, 16 m ; 1 ♂ MNHN-IU-2013-4875 (lot JL338), 1 ♂ MNHN-IU-2013-5963 (lot JL338), st. GR07, 24 m; 1 ♂ MNHN-IU-2013-4876 (lot JL382), st. GR 11, 13 m; 3♂, 2 ov. ♀ MNHN-IU-2013-5927 (lot JL728), st. GR 23, 20 m.

DIAGNOSIS. — Pelia mutica and P. rotunda are distinguished in this work following Rathbun (1925), but the characters used to separate them are perhaps not of species level, as indicated by this author. In P. rotunda gastric and cardiac regions are more swollen, rostrum is more deflexed, width of carapace at hepatic regions relatively greater; spine at external angle of basal antennal article a little longer.

HABITAT. — On subtidal coral reef slope, sometimes with sponges. Collected 16-24 m, reported 1- 190 m.

DISTRIBUTION ( Melo 1996). — Western Atlantic. Brazil (from Pará to Rio Grande do Sul), Uruguay, and Argentina. Lesser Antilles ICA ( Guadeloupe).
