440 THE VOYAGE OF H.M.S. CHALLENGER. 



Bate, followed by five pairs of pereiopods. The pleopods or swimmerets consist in the 

 male, as well as in the female, of only three pairs." 



He still thinks it represents a new family of Hyperidae, to he placed next to the Phronimse. It 

 approaches the Typhidse, he says, by " the elongate shape of the head, with the mouth 

 underneath and the claws terminating the gnathopods. On the other hand, however, the 

 want of the second antennae in the male, the elongate slender shape of its first antennae, 

 whicli show nothing of the enlargement and the olfactory hairs peculiar to the male TyjMds, 

 and the want of the palpus in the male mandible, show that it differs widely from the 

 Typhidx." 



He now defines it thus : — 



" Caput oblongum, ooulis maximis superiorem capitis partem togeutibus. Segmenta thoracica 

 septem, abdominalia quinque. Antennarum in utroque sexu par unum. Mandibulse et 

 maxillae minimaj. Maxillipedum par unum conjunctum. Pedum thoracicorum paria septem, 

 anteriora duo parva et chelis armata. Pedum abdomiualium paria tria." There is no doubt, 

 he says, that Thaumops pelhicida is a pelagic Crustacean, retreating sometimes to considerable 

 depths, and coming up only in the night.

This is a letter remarking that Tliaumo^is pellucida "has been already described by Gu^rin- 

 !Meneville under the name of Cijsfnsoma nepitwm," and that the female caught in the Atlantic 

 "had a length of 84 mm., not of 14 mm.," as had been erroneously reported.

The new species is compared with " Callisoiiia Ilojjei and C. crenata," which it is said to resemble 

 in the first and second gnathojioda, and in the coxa of the five anterior pairs of appendages, 

 " but those of the fourth pair of pereiopoda considerably deeper than the ones appertaining 

 to the fifth pair." " The basis in the fourth pair" of pereiopoda "considerably broader and 

 higher than in the fifth pair." There are notches on the dorsal surface of the fourth and 

 fifth pleon-segments. "Telson deeply cut, but single."

In this extract, Catta says, " en resume, des Amphipodes normaux sont deja reprosent^s, dans le 

 Golfe de Marseille, par une trentaine de genres, dont un au moins nouveau, et par soixante- 

 dix a soixante-quinze espfeces diflferentes. Six especes nouvelles et deux varieties, de 

 formes svL'-tout adriatiques, donnent pour ainsi dire la physionomie de la faune locale."
