Pisces. 



The collection of fishes, though a small one, is very interest- 

 ing The marine fishes n" 1 — 5 and n^ 8 were presented to 

 Mr. Neervoort van de Poll by Mr. van Lier at Curacao. 

 The numbers 6, 7 and 9 were captured by Mr. Neervoort 

 van de Poll himself. 



The rarest of all is certainly Serrarms tigrinus^X. {n^ 2)^ 

 a fish the origin of which was up to this time supposed to be 

 the East-Indian sea, and which in this collection is found 

 together with Myripristifs jacobus Cuv. & Val., Pomacanthus 

 paru BL, Gobius soporator Cuv. & Val., and Muraena ca- 

 tenata BL, all well-known West-Indian forms. 



Blennius crinitus Cuv. & Val. (n" 5) , originating , accord- 

 ing to Cuvier, from the sea in the neighbourhood of la Ro- 

 ebelle, was captured near Cura9ao, which sustains Giin- 

 ther's statement, who mentions a specimen from Pernambuco. 



The freshwaterfishes (n" 6 and 7j , belonging to the 

 curious family of C y p r i n o d o n t i d a e , were captured 

 in the very small rivulets of Curasao and Aruba. As to 

 the habitat of these small viviparous fishes , Prof K. Mar- 

 tin informs me, that when the Expedition visited Aruba (in 

 the dry period) the water of the pool filled a groove of a 

 width of about ^/j meter and a depth of only some centi- 

 meters. The rivulet of Curacao was not so destitute of water 

 as that of Aruba , whereas in the pool of Bonaire almost 

 no water was to be seen.

 One badly preserved specimen from Curasao. 



2. Serranus tigrinus , Bl. 



D. 10/12. A. 3/8. 



Our specimen has a length of 93 ra.m, and differs from 

 the figures of Bloch (t. 237) and Seba (III. 27. 15 instead 

 III. 27. 5 as is quoted by Cuvier and Günther) , in having 

 the back of a dark color and only 4 cross-bands , viz. :
