OF SOUNDINGS. 5 



E, No. 7, 98 fathoms ; lat. 40° 05' 45"; long. 70° 55' 35". 

 This is a coarse clean sand, with black specks, with a few minute bits of shells. 

 No Infusoria nor Polythalamia were detected in it. 



E, No. 9, 51 fathoms ; lat. 40° 21' 54"; long. 70° 55' 35". 



A greenish gray mud or fine sand, with a few bits of shells. It contains a 

 considerable abundance of Polythalamia, among which were noticed Marginulina 

 Bacheii, fig. 5, not abundant ; Robulina D'Orbignii, fig. 9 and 10, and Buhmina 

 auriculata, fig. 25 to 27. 



SECOND LINE OF SOUNDINGS. 



From line F, about S. E. from Fire Island Inlet. 



F, No. 19, 111 fathoms ; lat. 40° 24' 40"; long. 73° 41' 20". 



This specimen is composed of a quartzose sand with black specks. It pre- 

 sented nothing of interest. 



F, No. 27, 20 fathoms; lat. 40° 14' 13"; long. 73° 21' 20". 



In this were found numerous small plates of an echinoderm ; also one spine 

 of an Echinus, and a single specimen of Ctuinqueloculina occidentalis, Bail. See 

 fig. 46 to 48. 



F, No. 24, 49 fathoms ; lat. 39° 52' 40"; long. 72° 14' 00". 



This is a greenish gray and rather coarse sand, mixed with some mud. By 

 levigation it yielded a few spiculse of sponges, a small cypriform crustacean shell, 

 and one spine of an Echinus. Polythalamia are rather abundant in this locality, 

 and among them were noticed Marginulina Bacheii, fig. 5, rather common ; 

 Orbulina universa, fig. 1, rare ; a small Bulimina, and a few small specimens of 

 Globigerina. 



F, No. 25, 105 fathoms ; lat. 39° 41' 10"; long. 71° 43' 00". 



This is a fine grayish green sand, very rich in small Polythalamia, particularly 

 in the species of Globigerina represented in fig. 20 to 22 ; Marginulina Bacheii, 

 fig. 5, is present, but rare ; a triangular species of Textularia (T. atlantica Bail., 

 fig. 38 to 43,) is also rather rare ; the species of Rotalina (R. Ehrenbergii Bail.) 

 represented in fig. 11 to 13, is quite common. By levigation this specimen 

 yielded some spiculse of sponges, fragments of Coscinodisci, one specimen of 

 Triceratium alternans, fig. 55 and 56; many frustules of Gallionella sulcata, Ehr.; 

 and some excessively minute spherical bodies (see fig. 49) which may possibly 

 be the ova of Polythalamia. 



THIRD LINE OF SOUNDINGS. 



From line G, about east from Little Egg Harbor. 



G, No. 12, 10 fathoms ; lat. 39° 30' 20"; long. 74° 10' 40". 



In the coarse, clean, quartzose gravel, of which this specimen is chiefly com- 

 posed, I noticed one small pebble of fossiliferous limestone, fig. QQ., containing
