Fi(i. 1. 



Fig. 1. — Batlnjnectcs longiiKs. Dorsal view, showing the five teeth of the antero- 

 lateral margins. The chelipeds are in a half-extended condition ; their pro- 

 l^odites (hands) are shown resting against the carpal spines. The specimen 

 shows an abnormality in the union of the two anterior marginal teeth of the 

 right side to form a single bifid tooth. 



Fio. 2. 



Fig. 2. — Bathjnectes longipes. Dorsal view, showing the i)osition of the chelipeds 

 after flexion of the wrists (carpopodites) as well as of the hands. The left 

 cheliped is in the attitude assumed by the crab whun imbedded in sand ; the 

 antero-lateral teeth are seen to form a sieve above the orifice of the inhalant gap 

 between cheliped and carapace. On the right side the arm (meroi)odite) of the 

 cheliped does not rest in its proper position beneath the enlarged po.-;terior 

 marginal tooth ; hence the inliahmt gap is imperfectly formed, and its aperture 

 is imperfectly covered by the marginal teeth.
