the form figured by Claus (1872. p. 140, pi. vii, fig. 26) and fiy Hansen (/.r.), although 
they are in a less advanced stage of development. In some, Out not in nil. there is a 
small “ zoea-spine on the hind margin of the carapace. 
6. Pseudo squilla, sp. | Pseuderichtlius elongcitus , Hansen |. 
Pseuderichthus elongatus, Hansen, 1895, 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 Claus (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 qlahriuscula (Lamarck) | Lysierichthus edirardsn (Eydoux and 
Souleyet)]. 
Lysierichtlms Edwanhii (Eyd. and Soul.), Hansen, 1895, p. 75, pi. vii, tigs. 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 clactylus cannot yet be made out. 
A post-larval specimen, 8 ’ 5 mm. in length, from Station 40 (off 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.

Occurrence. —Stations 126 and 127. Near Three Kings lsiai 
Surface-plankton. Three specimens (larvae). /(J/ 2 ) / r\ 
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 1 1 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 differing 
from all known species of the genus except the form described by Thomson (1882,
