Synalpheus shrimps (Crustacea: Decapoda: Alpheidae). I. The Gambarelloides group, with a description of a new speciesThe genus Synalpheus Bate, 1888, is one of the most diverse and widely distributed generaof caridean shrimps in the world. Often known as snapping shrimps because of the popping soundmade by the major first pereopod when the chela is closed rapidly, members of this genus areimportant components of coral reef and live bottom communities in all tropical and subtropical seas.The Gambarelloides group (a well-defined, homogeneous group within the genus but lackingformal subgeneric status) contains over half the described species of Synalpheus in the Gulf ofMexico and Caribbean. Its many species are distinguished from each other by subtle, and oftenvariable, characters. Accurate inventories of the Gulf fauna have been handicapped by difficulty inseparating these shrimps at the specific level. Distributional data, diagnoses, and references toeach of the 19 species of the group from the Western Atlantic Region are presented in this report.The 11 species known from the Gulf of Mexico are illustrated. Details of specific ecological associations,morphological variation, and life history strategies are also summarized. (Document has 125 pages.)

Holothurians (Echinodermata: Holothuroidea)A total of 213 holothurians, representing 16 species, was collected during Project Hourglass, a28-month systematic survey of ten stations along two transects (6-73 m) off central western Florida.This material, supplemented with 8 1 additional Gulf of Mexico specimens supplied by the FloridaDepartment of Natural Resources, brings the total number of species reported in this paper to 20. Ofthese species, 19 have previously been reported from the Gulf of Mexico. One, Allothyone mexicana,can be considered endemic to the Gulf of Mexico, and another, Thyone crassidisca, was recentlydescribed from material including Hourglass specimens. Systematic accounts, pertinent ecologicaldata and line drawings of taxonomically important skeletal elements are included for each species.Keys to all 60 holothurian species known from the Gulf of Mexico are provided. Range extensionsfor several species are noted. (Document contains 79 pages.)
