STOMATOPODA— CALMAN. 143 



the form figured by Glaus (1872, p. J 40, pi. vii, tig. 26) and by Hansen {I.e.), although 

 they are in a less advanced stage of development. In some, but not in all, there is a 

 small " zoea-spine " on the hind margin of the carapace. 



6. Pseudosquilla, sp. [^Pseuderichthus elongatus, Hansen]. 



Pseuderichthus elongatus, Hansen, 189.5, p. 86. 



Occurrence. — Stations 45, 46, 47, 49, 50. South Atlantic, off Brazilian coast. 

 Surface-plankton. Nine specimens. 



Remarks. — The specimens range from 12 to 20 mm. in total length. They differ 

 from the specimen of 47 mm. length figured by Glaus (1872, p. 140, pi. vi, fig. 25) in 

 having a small denticle below the postero-lateral spine on each side of the carapace, 

 and 'in the shorter ventral process of the uropods, which does not extend beyond the 

 telson. 



7. Lysiosquilla glabriuscula (Lamarck) [Lysierieht/ms edwardsii (Eydoux and 



Souleyet)]. 



Lysiericldhus Edwardsii (Eyd. and Soul.), Hansen, 1895, p. 75, pi. vii, figs. 4-4e, 5-5c (with 

 synonymy). 



Occurrence. — Station 58. Equatorial Atlantic. Surface-plankton. One specimen 

 (larva). 



Remarks. — The specimen, which measures 20 mm. in total length (including 

 rostrum), agrees very closely with Hansen's account of the later stages of L. edwardsii, 

 although the number of teeth on the raptorial dactylus cannot yet be made out. 



A post-larval specimen, 8 • 5 mm. in length, from Station 40 {oE Rio de Janeiro 

 Harbour, plankton at 2 metres depth), may be mentioned here, although its specific 

 and even generic position remains obscure to me. It has the general characters of a 

 Lysiosquilla, except that the chela of the fourth thoracic limb is of similar shape to, 

 and little wider than, the fifth ; the raptorial limb has eight teeth on the dactylus 

 (including the terminal one), and the uropod has seven spines. 



8. Lysiosquilla, sp. '[Lysierichthus, sp.]. 



Occurrence. — Stations 126 and 127. Near Three Kings Islands, New Zealand. 

 Surface-plankton. Three specimens (larvae). 



Stations 133, 135, and 136. Spirits Bay, New Zealand. Plankton, surface to 

 20 metres depth. Many larvae, one post-larval specimen. 



Remarks. — The post-larval specimen from Station 135 measures about 11 mm. in 

 length. Its general characters and, in particular, the form of the last two pairs of 

 chelipeds, indicate that it belongs to the genus Lysiosquilla. It has, however, only four 

 teeth (including the terminal one) on the dactylus of the raptorial limbs, thus diff"ering 

 from all known species of the genus except the form described by Thomson (1882,
