Remarks.

Galacantha spinosa was collected off Laguna Madre, Tamaulipas (WNW); Tuxpan, Veracruz (WSW), Términos Lagoon, and San Pedro and San Pablo rivers, Campeche (SSW); 640-1144 m. This species was most abundant in the SSW sector and in autumn (42.5% and 37. 5%, respectively). Overall sex ratio favored males 1.4: 1 F, but this difference was not statistically significant. Females reached larger sizes CL x - = 34.3 ± 4.798 (min. 27.0, max. 43.0 mm) than males x = 30.5 ± 7.111. (min. 14.8, max. 40.0). The ovigerous females (CL = 23.6 to 35.4 mm) occurred in spring, summer, and autumn at a 735-1016 m depth range. One female (CL = 20.5 mm) was infested by bopyrid. These are the first records in sectors WSW and WNW; also, we increase the deeper bathymetric limit to 1144 m.
