From tlie same locality— station 150— there are two small individnalM 

 (male and female), which I consider as undeveloped individuals ol' 

 P. andersojii; one is in a similar shell to that which holds the adult 

 type, with an investing anemone, while the other is in a Natica. In tho 

 larger specimen the carapace measures only 7 mm. in lengtli. lioth 

 exhibit much less relative elongation of the chelipedcs aud ambulatory 

 legs, rendering it probable that elongation is a special character of 

 adult males. The joints of tlie right chelipede are more definitely 

 subspinose, especially the under surface of the mei'us and the ed^-es 

 of the hand and fingers, but the subspiuiform granulation can of couisc 

 only be made out with a lens. The hand is broader than in tlie adult, 

 and more ovate in shape. In one specimen only two denticles can be 

 made out at the apices of the ophthalmic scales, but in the other 

 specimen there are three denticles. 



13. * Parapagurus mimdus, n. sp. 



Station 150, off the north Maldive Atoll, deptli 719 fathoms. 

 Nine specimens — all living in Dentalium shells — including two females 

 with ova. The shell tenanted by tlie largest example is covered by a 

 colony of Epizoanthus, composed of four polyps. 



In this minute species, which appears to be fully adult, as shown 

 by the presence of eggs, the largest example has the carapace, chelipedes, 

 and legs glabrous with a white porcellanous aspect. In the smaller 

 specimens there is a slight pubescence on all the above named parts, 

 including the eye-stalks, where the hairs may be rather long. Hairs 

 are met with in this last situation even in the lai'gest specimen. 



The anterior portion of the carapace is glabrous and regularly 

 convex, with the exception of a slight wrinkling antero-laterally. The 

 median frontal projection is scarcely indicated. The eye-stalks exhibib 

 considerable basal dilatation, and the narrowed apex carries a reduced 

 but deeply pigmented cornea. The ophthalmic scales are minute, and 

 terminate in a subacute point. The antennal peduncles slightly exceed 

 the eye-stalks ; the acicle is almost straight, ciliated, and faintly 

 spinose on its inner margin ; the external prolongation of the second 

 joint exhibits considerable depth, and its apex can scarcely be termed 

 acute. The antennular peduncles exceed the eye-stalks by more than 

 the length of the last peduncular joint— this however is almost a 

 generic character. The antennal flagellum is apparently not longer 

 than the body, if as long. 



The right chelipede has the joints of a white porcellanous aspect. 

 The hand (omitting the fingers) is slightly longer than the carpu.s, 

 but the proportion seems to vary slightly in different .specinicus.
