preceding it has been hitherto a desideratum to the Museum 

 collection*. 



There is also in the collection a small specimen of Penceus 

 which, on account of the imperfection of the rostrum, I cannot 

 at present determine with certainty. 



Stenopus MsjpiduSj Latr. 

 New Guinea (an adult female of large size). 



Stomatopoda. 



Lysiosquilla maculata (Fabr.). 

 Goram (a young male) . 



Squilla nepa, Latr. 

 West Borneo (an adult female). 



Pseudosquilla ciliata (Fabr.) . 

 New Guinea (an adult female). 



* The following additional species have been lately received by the 

 British Museum : — 



Penmis Macleayii, Haswell. 



A specimen has recently been purchased (together with one of P. 

 cnnaliculatus) from Mr. A. P. Goodwin, who collected them at the mouth 

 of the Richmond River, New South Wales. Mr. HasweU's types were 

 from Port Jackson. This species, with several others still desiderata to 

 the Museum, has been described by him since the publication of my 

 paper. Its place in the classification is in the vicinity of P. affinis and 

 P. avirostris. 



Penceus Joyneri, sp. n. (Plate XV. figs. 8-10.) 



Carapace more or less pilose above, with the antennal and gastro- 

 hepatic sulci faintly indicated ; no pterygostomian spine. Rostrum 

 nearly straight, acute, slender, and not reaching to the end of the an- 

 tennal scale, armed above with seven or eight teeth, of which the poste- 

 rior three are situated on the carapace behind its anterior margin, the 

 last being separated from the rest by a wider interval ; the anterior third 

 of the upper margin and the lower margin are without spines. A lon- 

 gitudinal median dorsal line on the surface of the carapace indicates the 

 obsolete dorsal ridge ; and a similar line exists on the first three post- 

 abdominal segments. The first segment has a rounded tooth on each 

 lateral margin. The fourth to sixth postabdominal segments are acutely 

 carinated above. The terminal segment has a longitudinal median 

 groove on its dorsal surface ; its lateral margins are without spines ; and 

 its distal end is produced and acuminated. The eyes are large, the 

 antennulary flagella very short ; the exognathi of the outer maxillipedes 

 scarcely reach beyond the end of the penidtimate joint. The second 

 joint of the first and second legs (in the male) is armed with a spine
