76 Dr. A. B. Meyer on Hyalonema cebuense. 



Nymphon gracilipes, n. sp. 



Very slender, clothed with very short hairs. Legs very 

 long. Head and neck of equal length, together about as long 

 as the body. First (mandibular) pair of palpiform appendages 

 three-jointed, terminating in slender chelge ; second pair five- 

 jointed, the first joint very small, the second the longest, the 

 remaining joints very hairy ; third (ovigerous) pair eleven- 

 jointed, the first joint very short, second, third, and fourth 

 longer, fifth very long, sixth to tenth gradually decreasing in 

 size, the eleventh minute. Legs with the first and third joints 

 very short, the second rather longer, the fourth to sixth very 

 long, the seventh and eighth (first and second tarsal) subequal, 

 straight. Claws two, one very small.

Nymphon styligerum, n. sp. 



Rather robust, hairy ; legs short. Head sessile, very thick. 

 First (mandibular) pair of palpiform appendages rudimentary 

 or abortive, a single joint only being developed ; second pair 

 five-jointed ; third (ovigerous) pair ten-jointed, with the first 

 three joints short, the fourth and fifth longer, the sixth to the 

 ninth short, the tenth quite minute. Legs with the first three 

 joints very short, the next three joints longer, the seventh (first 

 tarsal joint) minute, the eighth (second tarsal) longer, curved. 

 Claws two, unequal. Abdomen terminating posteriorly in a 

 long styliform process. 



Length -^ inch.

Should the form of the first pair of palpiform appendages 

 prove constant, this species would probably constitute the type 

 of a new genus allied to Achelta, Hodge.

Dear Sirs, 



Messrs. Higgin and Carter describe and figure, in the last 

 number of your Journal (June, p. 377, plate xxi.), Hyalonema 

 cebuense, a new hexactinellid sponge from Cebu, Philippine 

 Islands. It is j ust a year now that I sent the enclosed photo- 

 graph to the late Dr. J. E. Gray. I received this photograph
