tooth situated just before the middle. The orbital margin runs somewhat as a S, but there 

 is no tracé of an orbital tooth. The three other spines on the side of the carapace are acute, 

 and, as regards the hepatic and cervical grooves and carinae, this species fully resembles the 

 atlantic Pen. serratus. According to Spence Bate the "Challenger" species should bear 12 

 or 13 teeth on the rostrum, the smaller number occurring in our specimen may be due to its 

 younger age. 



Abdomen and telson agree with Bate's description; the tip of the telson reaches a little 

 beyond the spine on the margin of the outer uropod, but the telson is distinctly shorter than 

 the endopod of the caudal fan. 



The eye-peduncles and the tvvo pairs of antennae agree with the description and the 

 figures in the Challenger Report. The 3""'' article of the antennular peduncle extends as far 

 forward as the obtuse, inner extremity of the scaphocerite ; the upper flagella are a little shorter 

 than the peduncle, the lower are incomplete. 



The external maxillipeds reach to the end of the penultimate antennular article. 



With regard to the thoracic legs, I wish to remark that I did not observe an ex op o d 

 on any of these legs, and therefore this species was first referred by me to the genus 

 Parapenaeïts and considered to be related to Parap. rectaaitus : this fact is perhaps also due to 

 the young state of this specimen. The three anterior legs bear an epipod. The first pair of legs 

 that are bispinose, reach w^ith the fingers beyond the antennal peduncle, the 2"*^ to the end of 

 the eye-peduncles and the 3"' reach with their chelae beyond them ; the 4''^ are but a little 

 longer than the i^' and the 5''^ are as long as the external maxillipeds. In the 5''^ pair of legs 

 the merus is as long as the carpus, the propodus only a little more than half as long and 

 the dactylus measures hardly one-third the length of the merus. The sternum is armed, as in 

 Penaeopsis serrahis A. M.-Edw., var. antüleiisis, with a median spine between the bases of the 

 -th legg a^,i(j \s\x[\ another smaller one between those of the 4"^ but the rounded tubercle that 

 in the variety antillensis occurs at either side of the posterior spine, is wanting in this specimen. 



There is no tracé of a petasma. 



General distribution: Fiji Islands (Spence Bate); Torres Strait (Spence Bate).

 {Neopenaeopsis Bouvier). 



The genus Parapcnacits, as restricted by Alcock and Bouvier, is at present represented 

 by 8 species, 4 of which are inhabitants of the Atlantic Ocean and the Mediterranean, while the 

 other 4 are distributed through the Indopacific. Parap. longirostris (H. Luc.) occurs not only in 

 the Mediterranean and the Adriatic Seas, from the shores of Asia Minor to those of Spain, 

 but has also been observed in the East Atlantic from the coast of Portugal to that of Morocco. 

 This species is represented on the east coast of the United States by Parap. polihis S. I. Smith, 

 which, however, has also been observed in the Gulf of Paria. Parap. paradoxus Bouv. inhabits 

 the Gulf of Mexico and is, probably, closely related to Parap. politus, a species which is still 

 insufiïciently known. The fourth atlantic form is Parap. aiuericamis Rathb., that occurs in the
