These specimens reached the largest sizes of the species reported in literature. Key-words: Triakidae, Mustelus fasciatus, maximum length, Uruguay, South Western Atlantic. Introduction – The Striped smooth-hound Mustelus fasciatus (Garman, 1913) is a shark endemic to a restricted area of the inner continental shelf (South Brazil to Argentina) in the Southwest Atlantic Ocean. High fishing pressure on this species is reported in the southern Brazil. In Uruguay M. fasciatus is sporadically caught by local fisherman with gillnets and trawlers. This specie was described by Garman in 1913 on the basis of juvenile individuals. The first adult specimen was collected in the Uruguayan waters (Sadowsky, 1977), and later, a few adult specimens were sited from Uruguay and the southern and northern coasts of State of Rio Grande do Sul, Brazil (Soto, 2001a). This note reports the largest specimens documented in literature. Materials and methods – The two specimens reported in this note were identified according to Compagno (1984). The first specimen, a female, was caught on October 15 th 2007, by trammel net of the fishing boat Lina Valeria III off S. E. Punta del Diablo, Rocha, Uruguay (approximate coord. 34°10'S-53°16'W on sandy-muddy bottom at 18 m depth (Fig.1a-c). This specimen is stored in a Belgian private collection. The second shark, a male, was caught in Pozo de Fango off La Paloma, Rocha, (approximate coord. 34°47’50S-53°48’50W) by a trammel net, on November 15 th 2009, at 70 m depth (Fig. 1d). This specimen will be taxidermies and stored in the “Wilderness Studi Ambientali” collection in Palermo. Both specimens were measured as total length (cm) and weighted as total weight (kg). Other biometries were taken only in female. Results – M. fasciatus female was 177 cm total length and 29,7 kg weight. Other significant biometries were: Head (41 cm), Trunk (54 cm), Tail (82 cm), Caudal fin length (36 cm), Second dorsal fin length (23 cm), Interdorsal space (52 cm), Pectoral fin length (25 cm), Precaudal tail (47 cm), Precaudal height (5.5 cm), Dorsal fin base (25 cm), Dorsal fin height (14 cm), Pectoral fin base (11 cm), Internasal distance (5.0 cm), Preoral length (12 cm), Mouth width (12 cm).
