The Matutidae are distinguished from the Calappidae by 
their “‘ maxillipeds closing the buccal cavern ; the palp hidden,” 
and from the Leucosiidae by having their “‘ afferent branchial 
openings in front of the bases of the chelipeds.”

For numerous references in addition to those supplied in 
connection with the specific discussion, and for a full treatment 
of the characters distinctive of the family and genus, Alcock’s 
work should be consulted. Among other features of the genus 
it may be noted that ‘“‘ on removal of the external maxillipeds 
a deep undivided efferent canal is seen in the roof of the endos- 
tome, which groove is closed below by an elongate lamellar 
process of the first pair of maxillipeds.” Also “the four 
ambulatory legs have the form of swimming-paddles, the two 
terminal joints being broadened and compressed—in the first 
and last pairs of legs enormously so.” Curiously Ruppell and
