20 Messrs. J. Wood-Mason and A. Alcock on 



Clupcida3, or even in a new family next to the Clupeidge. 

 Admittino; its present position, it is the first Clupeoid yet 

 discovered in the depths. 



5. Dysommopsis is a new Muraenid closely allied to Dy- 

 somma, with which singular form it may be included in anew 

 alliance. It differs most conspicuously from Dysomma in 

 wanting pectoral fins. 



Upon the new species of known genera a few general 

 remarks may be made. Two species of Dihranchus — one 

 from the Andaman Sea, the other from the Bay of Bengal — 

 represent here a type hitherto known only from the African 

 side of the Atlantic. 



Callovhynclins^ PJiysiculus^ Ateleopus, and with them Neo- 

 scopelus and Dihranchus, may perhaps be looked upon as 

 additional links in the chain which appears to connect the 

 local bathybial fauna of the Bay of Bengal with the fauna on 

 the one hand of the west Atlantic and on the otlier hand of 

 the Japan seas. 



In Sehastes hexanema, Lioscorjnus lonrjiceps^ Peristethus 

 Murrayi, and Scopelus engraulis we have further instances of 

 the existence at moderate depths in the Indian seas of types 

 discovered by the ' Challenger ' at similar depths in the seas 

 of the East-Indo-Australian Archipelago, such as our previous 

 experience would lead us to anticipate. 



A new species of Ilarpodon deserves a word of remark. 

 It ap])ears to be very near to Ilarpodon microchir from Japan, 

 but difters from it and equally from Ilarpodon nehereus in its 

 more complete squamation, the whole body and the greater 

 ])art of the head being covered with thin rather deciduous 

 scales. 



Lastly, the discovery that the small Brotuline Ophidiid, 

 Saccogaster macidata, the male of which is furnished with a 

 bilobed external genital organ, is viviparous, though not par- 

 ticularly appertaining to bathybiology, is interesting enough 

 to call for notice, for it confirms the opinions which have 

 been formed of the function of similar a])pcndages in the males 

 of other Brotuline Ophidiids — c. g. Dincmatichthys ihioca'te- 

 oides, Blkr., and Bythites fuscus, Beinhardt.
